Answer:

The percent composition (by mass) of a compound can be calculated by dividing the mass of each element by the total mass of the compound.

Explanation:

The percent composition of a compond is calculated with the molecular formula: divide the mass of each element found in one mole of the compound by the total molar mass of the compound.

Answer:

Here is an example of this using the compound C2OH4

You will first need to find the molar mass of the compound.

  • C = 2 x 12 = 24
  • O = 1 x 16 = 16
  • H = 4 x 1 = 4

Total mass = 40 amu

To find the percent composition you divide each part by the whole and multiply by 100 to convert to a %.

  • C = (24/44) x 100 = 54.5%
  • O = (16/44) x 100 = 36.4%
  • H = (4/44) x 100 = 9.1%
