Question

A compound is found to contain 0.167g of carbon, 0.0349 g of hydrogen, and 0.222 g of oxygen.

Determine the empirical formula of the compound and record it in the space below. [List the elements
in the order presented above (C, H, O) and write the subscripts as regular numbers. (Ex: H₂O would
become H2O)]

Answer 1

CH2O

Step-by-step explanation:

1. Convert grams to moles (Divide by molar mass)

Carbon: 0.167 / 12.01 = 0.013905

Hydrogen: 0.0349 / 1.01 = 0.034554

Oxygen: 0.222 / 16.00 = 0.013875

2. Divide by the lowest amount (Oxygen = 0.013875)

Carbon: 0.013905 / 0.013875 = 1.00

Hydrogen: 0.034554 / 0.013875 = 2.49

Oxygen: 0.013875 / 0.013875 = 1
