Question

A compound consists of 81.8% C and 18.2% H by mass. What is its empirical formula?​

Answer 1

Empirical formula of 81.8 carbon and 18.2 hydrogen

Steps

• Find the empirical formula of a compound that has 81.8% of Carbon (C), 18.2% of Hydrogen (H).
• Divide by fractional component of each mole value: C=1.5354936431103, H=4.0709872862205Round to closest whole numbers: C=2, H=4

Combine to get the empirical formula: C2H4
