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

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 C3H8?
Well, isn't that just a happy little question! To find the percent by mass of carbon in C3H8, you first need to calculate the molar mass of carbon in C3H8, which is 3 times the molar mass of carbon. Then, you divide the molar mass of carbon by the molar mass of C3H8 and multiply by 100 to get the percent by mass. Just remember, there are no mistakes in chemistry, only happy accidents!
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 acetone's percent composition by mass?
%C= 62.0% %H2= 10.4% %O2= 27.5% To find these, you divide the molar mass of the specific element in the compound divided by the molar mass of the entire compound.
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?

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?
To find the percent by mass of carbon in acetone (C3H6O), calculate the molar mass of carbon in acetone by adding the molar masses of the individual atoms: (3 × atomic mass of carbon) / molar mass of acetone × 100. This will give you the percentage of carbon in acetone by mass.
What is the percent composition of carbon in beryllium cyanide?
To determine the percent composition of carbon in beryllium cyanide, first find the molar mass of beryllium cyanide, then calculate the molar mass contributed by carbon. Finally, divide the molar mass of carbon by the total molar mass of beryllium cyanide and multiply by 100 to get the percent composition.
