An organic compound contains 69% carbon, 15.3% hydrogen and 30.7% oxygen. Calculate the the empirical formula [C=12, H = 1, O = 16]

A

C\(_4\)H\(_12\)O

B

C\(_3\)H\(_9\)O

C

C\(_4\)H\(_9\)O

D

C\(_3\)H\(_8\)O

correct option: d

C  \(\frac{69}{12}\)   H  \(\frac{15.3}{1}\)     O  \(\frac{30.7}{16}\)

C = 5.75
H = 15.3
O = 1.92

C \(\frac{5.75}{1,92}\)    H  \(\frac{15.3}{1.92}\)     O  \(\frac{1.92}{1.92}\)

C\(_3\)H\(_8\)O
