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 = [tex]\frac{individual mass of the element}{total mass of the compound}[/tex] x 100
For carbon,
[tex]\frac{13.18}{16.5}[/tex]x 100
percent composition of carbon = 79.87 % of carbon.
for hydrogen:
[tex]\frac{3.32}{16.5}[/tex]
= 20.12 % of hydrogen
In the compound given 79.87 % of carbon and 20.12% of hydrogen is present.
