To find the mass of carbon as a percent of the molecule, you have to first know the mass of the whole molecule. This can be done with the atomic weights of the elements and multiplying them by the number of atoms in a single molecule of hexachlorophene (the given compound).
Carbon: 12.0 g/mol × 13 = 156
Hydrogen: 1.0 g/mol × 6 = 6.0
Chlorine: 35.5 g/mol × 6 = 213
Oxygen: 16.0 g/mol × 2 = 32.0
C13H6Cl6O2 = 407 g/mol
(Mass of carbon ÷ total mass) × 100 = % carbon by mass
(156 ÷ 407) × 100 = 38.3% carbon
To calculate the percent of carbon by mass in C4H10O, first determine the molar mass of the compound: C = 12.01 g/mol, H = 1.008 g/mol, O = 16.00 g/mol. The total molar mass of C4H10O is 74.12 g/mol. Then, calculate the mass contribution of carbon: 4(12.01 g/mol) / 74.12 g/mol = 0.648. Finally, convert this to a percentage by multiplying by 100% to get 64.8% carbon by mass.
First find the molar mass of C10H14N2 by multiplying the number of atoms of each element times its molar mass (atomic weight on the Periodic Table). Then add the molar masses of each element. The sum is the molar mass of the compound.
C: 10 x 12.011g/mol = 120.11g/mol
H: 14 x 1.008g/mol = 14.11g/mol
N: 2 x 14.007g/mol = 28.014g/mol
-----------------------------------------------
Total = 162.23g/mol = molar mass of C10H14N2
Percent carbon by mass = mass of C/mass of C10H14N2 x 100 = (120.11g/mol)/(162.23g/mol) x 100 = 74.037% C by mass

What is the percent by mass of carbon in 44g of carbon dioxide?
The molar mass of carbon dioxide (CO2) is 44 g/mol. Carbon has a molar mass of 12 g/mol and oxygen has a molar mass of 16 g/mol. So, in 44g of CO2, there are 12g of carbon. Therefore, the percent by mass of carbon in 44g of carbon dioxide is (12g / 44g) x 100 = 27.3%.
What is the percent by mass of carbon in 44 g of carbon dioxide?
To calculate the percent by mass of carbon in carbon dioxide, first determine the molar mass of CO2 (12 g/mol for carbon and 32 g/mol for oxygen). Then divide the molar mass of carbon by the molar mass of CO2 and multiply by 100 to get the percentage. In this case, the percent by mass of carbon in 44 g of CO2 is (12 g/mol / 44 g/mol) * 100 = 27.27%.
What is the percent by mass of carbon in C3H8?
To calculate the percent by mass of carbon in C3H8, you first need to determine the molar mass of the entire compound. C3H8 has a molar mass of 44 g/mol. The molar mass of carbon in C3H8 is 3 * 12 g/mol = 36 g/mol. To find the percent by mass of carbon, divide the molar mass of carbon by the molar mass of the compound and multiply by 100: (36 g/mol / 44 g/mol) * 100 ≈ 81.8%.
What is acetone's percent composition by mass?
Acetone's percent composition by mass is 62.13% carbon, 31.82% oxygen, and 6.05% hydrogen.
What is the percent composition of CO2?
Carbonic acid - H2CO3 Find the atomic masses of each element and multiply it by however many atoms are in the compound, then add them together. H = 1.007 × 2 = 2.014 C = 12.01 O = 16.00 × 3= 48.00 Molecular mass = 2.014 + 12.01 + 48.00 = 62.02 grams/mole Take the mass of a specific element (above) and divide it by the total molecular mass. Change the final answer to a percent Hydrogen: 2.014 ÷ 62.02 = .0325 = 3.25% Carbon: 12.01 ÷ 62.02 = .194 = 19.4% Oxygen: 48.00 ÷ 62.02 = .774 = 77.4% Carbonic acid contains 3.25% Hydrogen, 19.4% Carbon, and 77.4% Oxygen.
What is the compound name for C4H10O?
The compound name for C4H10O is butanol. It is an alcohol with a four-carbon chain and a hydroxyl functional group.
What is the mass percent of carbon in carbon monoxide?
The molar mass of carbon monoxide (CO) is 28.01 g/mol. The molar mass of carbon is 12.01 g/mol. To find the mass percent of carbon in CO, you divide the molar mass of carbon by the molar mass of CO and multiply by 100. (12.01 g/mol / 28.01 g/mol) x 100 = 42.9% Therefore, the mass percent of carbon in carbon monoxide is approximately 42.9%.
What is the percent by mass of carbon in aceton C3H6O?
