Question

A compound is 40% carbon, 6.7% hydrogen, and 53.3% oxygen. What is the empirical formula? (4 points)

Answer 1

Answer:

CH2O

Explanation:

Dividing by the atomic masses:

40 / 12 = 3.333

6.7 / 1 = 6.7

53.3 / 16 = 3.331

The ratios are

3.333/ 3.333 : 6.7 / 3.333 : 3.331/3.333

= 1:2:1.

So it is CH2O.
