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 percent of a composition of a compound containing 8.6g of Be and 52.4g of I?

To find the percent composition of each element in the compound, you first calculate the molar mass of Be (9.01 g/mol) and I (126.90 g/mol). Then, calculate the percent composition of each element by dividing the mass of the element by the total molar mass of the compound and multiplying by 100. The percent composition of Be is 5.14% and the percent composition of I is 94.86%.
