Recall that mass percent is given by:

% mass=mass of Xtotal mass×100

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.

88.14 g C×1 mol C12.01 g C = 7.34 mol C


11.86 g H×1 mol H1.01 g H = 11.74 mol H

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