We’re being asked to calculate moles of C.

We’re given the mass percent of the solution and we're going to use the **mass percent formula** shown below:

$\overline{){\mathbf{mass}}{\mathbf{}}{\mathbf{percent}}{\mathbf{=}}\frac{\mathbf{mass}\mathbf{}\mathbf{component}}{\mathbf{total}\mathbf{}\mathbf{mass}}{\mathbf{\times}}{\mathbf{100}}}$

Assume 100 g compound, well have 88.14 g C.

A compound isolated from the rind of lemons is found to be 88.14 % carbon and 11.86 % hydrogen by mass.

How many moles of C?
