Question

A sample of a compound analyzed in a chemistry laboratory consists of 5.34 g of carbon, 0.42 g of hydrogen, and 47.08 g of chlorine. What is the percent composition of this compound?

Answer 1

Answer:

10.1 % Carbon, 0.8 % Hydrogen and 89.1 % Chlorine.

Explanation:

The total mass of the compound is 5.34 + 0.42 + 47.08 = 52.84 g.

The percentage of carbon is:   $\frac{5.34}{52.84}$ × 100  = 10.1 %

The percentage of hydrogen is:  $\frac{0.42}{52.84}$ × 100 = 0.8 %

The percentage if chlorine is:  $\frac{47.08}{52.84}$ × 100 = 89.1 %
