# Problem: Fructose is a common sugar found in fruit. Elemental analysis of fructose gave the following mass percent composition: C 40.00%, H 6.72%, O 53.28%. The molar mass of fructose is 180.16 g/mol.Find the molecular formula of fructose.

###### FREE Expert Solution

Recall that mass percent is given by:

Assuming we have 100 g of the compound, this means we have 40.00 g C, 6.72 g H, and 53.28 g O.

Now, we need to get the moles of each element in the compound.

The atomic masses are 12.01 g/mol C, 1.01 g/mol H, and 16.00 g O.

= 3.33 mol C

= 6.65 mol H

= 3.33 mol O

Divide the number of moles of each by the smallest value.
