1. Calculate the molar mass of sugar (sucrose: C12H22O1 )
2. What is the percent composition of carbon in sucrose?
3. What is the percent composition of hydrogen in sucrose?
4. What is the percent composition of oxygen in sucrose?
Answer:
1. 342g/mol2. 42.1%3. 6.43%4. 51.46%Explanation:
Greetings !!!
First let's define the meaning of molecular mass.
Molar mass M is the mass of a chemical compound divided by its amount-of-substance measured in moles. It is defined as MB = m/nB, where m is the total mass of a sample of pure substance and nB is the amount of substance B given in moles. The definition applies to pure substance.
For the first question
solution
The atomic mass of carbon(C)= 12
The atomic mass of Hydrogen(H)= 1
The atomic mass of Oxygen(O)= 16
Molecular mass of sucrose(Table sugar)C₁₂H₂₂O₁₁=
12×(The atomic mass of carbon(C)) + 11×(The atomic mass of Hydrogen(H)) + 11×(The atomic mass of Oxygen(O))
Molecular mass of sucrose = 12×12+22×1+11×16
=144 + 22 + 176
=342g/mol
Secondly, when we look at percent composition first let's define it :-
Percent CompositionFind the molar mass of all the elements in the compound in grams per mole. Find the molecular mass of the entire compound.Divide the component's molar mass by the entire molecular mass.You will now have a number between 0 and 1. Multiply it by 100% to get percent composition.So, let's work on the questions
%Compositions
Carbon= 144/342×100 = 42.1%
Hydrogen = 22/342×100= 6.43%
Oxygen = 176/342×100= 51.46%
And to be more sure add those percent values
Thus, 42.1%+6.43%+51.46%= 99.99%

what is the volume, measured in liters at STP, of 285 grams of the gas acetylene, C2H2?
285 grams of acetylene at standard temperature and pressure (STP) have a volume of 24.45 liters.
How to find the volume of a gas?To find the volume of a gas at standard temperature and pressure (STP), you can use the ideal gas law: PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature.
STP is defined as 0 °C (273.15 K) and 1 atm (101.325 kPa)
First, we need to find the number of moles of acetylene. To do this, we use the molar mass of C2H2 which is 26.04 g/mol
n = m / M
n = 285 g / 26.04 g/mol
n = 10.9 moles
Then we can use the ideal gas law to find the volume in liters:
V = nRT / P
V = (10.9 moles) * (0.08206 Latmmol^-1*K^-1) * (273.15 K) / (101.325 kPa)
V = 24.45 L
Therefore, 285 grams of acetylene at standard temperature and pressure (STP) have a volume of 24.45 liters.

What is the molality of a solution containing
10.0g Na2SO4 dissolved in 1000.0g of water?
Answer:
Explanation:
Use the definition of molality to guide you to find what is needed to solve for molality.
molality = mol of solute/kg of solvent
Step 1: Find molar mass of Na2SO4
Na: 2 x 23.00 g = 46.00 g
S: 1 x 32.06 g = 32.06 g
O: 4 x 16.00 g = 64.00 g
Molar mass of Na2SO4 = 142.06 g/mol
Step 2: Convert 10.0 g Na2SO4 into moles using molar mass of Na2SO4 from step 1.
10.0 g x (1 mol/142.06 g) = 0.070393 mol
Note that grams cancel and you are left with moles.
Step 3: Convert 1000.0 g of water into kilograms of water. Remember that 1000 g = 1 kg.
1000.0 g x (1 kg/1000g) = 1.0000 kg water
Note that grams cancel and you are left with kilograms.
Step 3: Use the definition of molality to find molality for this solution. The solute is Na2SO4. The solvent is water.
Definition of molality = mol of solute/kg of solvent
molality = 0.070383 mol/1.0000 kg
molality = 0.070393 m
There are 3 significant figures in 10.0 g and 5 significant figures in 1000.0 g. Use the least number of significant figures when multiplying or dividing. In this case 10.0 g has the least number of significant figures. The final answer with the correct number of significant figures is 0.0704 m.

The pressure of a gas is directly proportional to its temperature. Hence, as temperature decreases pressure decreases. Therefore, option D is correct.
What is Gay- Lussacs law?
According to Gay- Lussacs law at constant volume, the pressure of a gas is directly proportional to the temperature.
Hence, P/T = constant.
Let P1 and T1 be the initial pressure and temperature and P2, T2 be the final quantities, then
P1/T1 = P2/T2
Given P1 = 1 atm
T1 = x ° C
T2 = x/2° C
Then P2 = P1 T2/T1
P2 = 1 × x/2° C / x° C

What is Mass Composition?By comparing an element's molar mass to the total molar mass of the compound as a whole, mass percent composition can be calculated. The final result of the calculation is a percentage that can be used to compare various compounds.
The exact number of atoms in the compound is shown by this formula.
The equation to calculate the percentage composition by mass of sodium is given below:
The exact number of atoms in the compound can be seen in this formula: mass of sodium = (22.99 g/mol) x (1 mole NaOH / 40.00 g/mol) = 0.5747 g % mass of sodium = (0.5747 g / 40.00 g/mol) x 100 = 1.43 % We can use the following equation to determine the percentage of the compound composed of oxygen by mass:
(mass of oxygen / molar mass of NaOH) x 100 = oxygen percentage = (16.00 g/mol) x (1 mole NaOH / 40.00 g/mol) = 0.400 g Oxygen percentage = (0.400 g / 40.00 g/mol) x 100 = 1.00% We can use the following equation to determine the percentage of hydrogen by mass:
(mass of hydrogen / molar mass of NaOH) x 100 = % mass of hydrogen % mass of hydrogen = (1.01 g/mol) x (1 mole NaOH / 40.00 g/mol) = 0.02525 g % mass of hydrogen = (0.02525 g / 40.00 g/mol) x 100 = 0.063% Na, 1.00% O, and 0.063% H The compound C12H22O11 has a We can use the same approach as before to determine the percentage of C12H22O11's elements by mass.

In light of this, there is one mol of NaCl in the solution.
Using the quantity of NaCl's moles, we must now determine the mass of NaCl.
Math processing error: Number of moles
58.44 g/mol is the molar mass of sodium chloride, which has a molecular weight of 1 mol.

So, to create a 1 M solution, we'll need 58.44 g of NaCl.
We will now talk about making a NaCl solution at a single molar strength.
A 1 liter volumetric flask can be filled with distilled water until it reaches the graduation mark, 58.44 g of NaCl and this amount of salt can be used to create a 1M solution of the salt.

The major chemical structures of hormones include
a. polysaccharides, esters, and steroids.
b. only molecules containing amine groups.
c. steroids, amino acid derivatives, and esters.
d. steroids, polypeptides, and anino acid derivatives.
e. only steroids.
Only steroids are included in the principal chemical structures of hormones. How atoms are organized within molecules is referred to as chemical structure.
What mechanisms govern chemical structures?By showing the spatial arrangement the atoms and chemical bonds within the molecule, chemical structure describes how a compound's molecular geometry is formed. A crucial visual depiction of a molecular formula is thus given to scientists in this way. The chemicals known as enantiomers are chiral and mirror-imaged.
How can chemical structures be distinguished?When determining the structures of chemical compounds, one often strives to determine the pattern and strength of bonding between all of the atoms in the molecule; if possible, one also looks for the three-dimensional spatial coordinates of a atoms in the molecule.
