Question

A sample of a given compound contains 13.18g of carbon and 3.32g of hydrogen. What is the percent composition of the compound?

Answer 1

The percent composition of the compound is 79.87 % of carbon and 20.12% of hydrogen

Explanation:

Given:

mass of carbon = 13.18 grams

mass of hydrogen = 3.32 grams

percent composition of compound =?

From the given data total mass of the compound is calculated

13.8 + 3.32

= 16.5 grams

The individual percentage of hydrogen and carbon will be calculated as:

percent composition  = $\frac{individual mass of the element}{total mass of the compound}$ x 100

For carbon,

 $\frac{13.18}{16.5}$x 100

percent composition of carbon = 79.87 % of carbon.

for hydrogen:

$\frac{3.32}{16.5}$

= 20.12 % of hydrogen

In the compound given 79.87 % of carbon and 20.12% of hydrogen is present.
