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?
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.
