We are asked to calculate for the **percent by mass (mass %) of C** in vanillin(C_{8}H_{8}O_{3})

and to do that we’re going to use the **mass percent formula** shown below:

$\overline{){\mathbf{mass}}{\mathbf{}}{\mathbf{percent}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{mass}\mathbf{}\mathbf{element}}{\mathbf{total}\mathbf{}\mathbf{mass}\mathbf{}\mathbf{of}\mathbf{}\mathbf{compound}}{\mathbf{\times}}{\mathbf{100}}}$

For the **percent by mass C**, we’re going to rewrite the equation as:

Based on the following structural formulas, calculate the percentage of carbon by mass present in each compound.

Vanillin (vanilla flavor)
