C3H6O
Correct answer is D
carbon = 72%, hydrogen = 12%, 16%
Dividing by the atomic weight we have for C = \(\frac{5}{1}\) = 6
H = \(\frac{12}{1}\) = 12
O = \(\frac{16}{16}\) = 1
Divide by the smallest number, we have = \(\frac{6}{1}\) = 6
H = \(\frac{12}{1}\) = 12
O = \(\frac{1}{1}\) = 1
The formula is C6H12O
