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
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

The 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)

carbon dioxide contains about 27.27% carbon.
Carbon cannot be stored in a specific area of the ocean, but the mass percent is 0.0028%
The chemical name for molecular formula C3H8 is propane. Propane has a weight of 44.10 grams per mole. Carbon (C) has a weight of 12.01 grams per mole. 1 mole of propane contains 3 moles of carbon. Therefore 81.70 percent by mass of propane is C.
From the formula of the compound, each molecular unit contains 2 copper atoms, 4 oxygen atoms, one carbon atom, and 2 hydrogen atoms. Multiplying each of these by its corresponding atomic mass gives 127 atomic mass units ("amu") of copper, 64 amu of oxygen, 12 amu of carbon, and 2 amu of hydrogen. Copper is clearly present in the largest percent by mass.
The percentage of carbon is 71,58 %.

carbon dioxide contains about 27.27% carbon.
C10H14O is called carvone or thymol. It has a total molar mass of 150.22 grams per mole, of which carbon is 79.96 percent by mass.
A hydrocarbon is a compond composed only of carbon and hydroge. Butanol, or C4H10O, is a compound oc carbon, hydrogen, and oxygen.
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.
Carbon has a atomic mass of 12.So its percentage is 75%
Carbon dioxide (CO2) has a molecular formula of one carbon atom and two oxygen atoms. To calculate the percentage of carbon in carbon dioxide, you take the molar mass of carbon (12.01 g/mol) and divide it by the molar mass of the entire compound (12.01 g/mol + 2*(16.00 g/mol)), and then multiply by 100 to get the percentage. This gives a percentage of approximately 27.3% carbon in carbon dioxide.
the answer is 6.3%
Carbon cannot be stored in a specific area of the ocean, but the mass percent is 0.0028%
Because the mass of carbon is not the same as that of oxygen.
Oxygen, carbon, hydrogen, and nitrogen together make up approximately 96% of your body mass. These elements are essential for forming the molecules and compounds that are found in your cells, tissues, and organs.
