Question

What is the empirical formula of a compound if a sample contains 5.97 grams of carbon and 0.99 grams of hydrogen?

Answer 1

Empirical formula is CH₂.

Step-by-step explanation:

Given data:

Empirical formula of sample = ?

Mass of C = 5.97 g

Mass of H = 0.99 g

Solution:

Number of gram atoms of H = 0.99 / 1.01 = 0.98

Number of gram atoms of C = 5.97 / 12 = 0.5

Atomic ratio:

C : H

0.5/0.5 : 0.98/0.5

1 : 2

C : H= 1 : 2

Empirical formula is CH₂.
