Question

PLEASE HELP : Chemical analysis of a clear liquid shows that it is 60.0% C, 13.4% H, and 26.6% O. Calculate the empirical formula of this substance.

Answer 1

Assume that you have a 100.0 g sample, and convert

the percentages to grams.

for C: 60.0% x 100.0 g = 60.0 g C

for H: 13.4% x 100.0 g = 13.4 g H

for O: 26.6% x 100.0 g = 26.6 g O
