Answer 1

CH₂

Step-by-step explanation:

Given parameters:

Percentage composition:

Carbon = 40.1%

Hydrogen = 6.6%

Unknown:

Empirical formula of the compound = ?

Solution:

The empirical formula of a substance is its simplest formula.

Elements Carbon Hydrogen

Percentage

Composition 40.1 6.6

Molecular mass 12 1

Number of moles 40.1/12 6.6/1

3.342 6.6

Divide through by

the smallest 3.342/3.342 6.6/3.342

1 2

So the empirical formula of the compound is CH₂
