use the experimental molar mass to determine the molecular formula for compiunds havin the following analyses?

Question

54.53%carbon, 9.15%hydrogen, and 36.32%oxygen; experimental molar mass 88

Answer 1

Divide 54.53 by 12, 9.15 by 1 and 36.32 by 16.

Then see how you can scale the numbers to get a whole-number ratio.

Then see how the apparent MW of the result fits into the number 88, and adjust accordingly.
