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

∙ 9y agoFirst 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

∙ 11y agoThe molar mass of C4H10O is 74.12. So you divide carbon (48.04) by the molar mass (74.12) and then multiply by 100. (48.04/74.12 * 100 = 64.81)
