# Problem: A compound isolated from the rind of lemons is found to be 88.14 % carbon and 11.86 % hydrogen by mass.What is the empirical formula?

###### FREE Expert Solution

Recall that mass percent is given by:

Assuming we have 100 g of the compound, this means we have 88.14 g C and 11.86 g H.

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

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

= 7.34 mol C

= 11.74 mol H

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