We are asked to calculate for the **percent by mass (mass %) of carbon (C) **in **C _{2}H_{5}Cl** and to do that we’re going to use the

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

First, we need to get the atomic weight of C in** C_{2}H_{5}Cl** using the periodic table and then calculate its molar mass.

**Mass of C:**

Calculate the mass percent composition of carbon in each of the following carbon compounds.

C_{2}H_{5}Cl
