A sample of a compound has a mass of 41.13 g. The sample is found to contain 37.28 g of carbon and 3.85 g of hydrogen. What is the percentage composition of the compound?

Answer 1

To find the percentage composition of the compound, we need to calculate the mass percent of carbon and hydrogen.

1. Calculate the mass percent of carbon:
% carbon = (mass of carbon / total mass of compound) x 100
% carbon = (37.28 g / 41.13 g) x 100
% carbon = 90.62%

2. Calculate the mass percent of hydrogen:
% hydrogen = (mass of hydrogen / total mass of compound) x 100
% hydrogen = (3.85 g / 41.13 g) x 100
% hydrogen = 9.38%

Therefore, the compound is composed of 90.62% carbon and 9.38% hydrogen.
