Figure out the **molar mass of the Cd(CH _{3})_{2}**

$\overline{){\mathbf{mass}}{\mathbf{}}{\mathbf{\%}}{\mathbf{}}{\mathbf{of}}{\mathbf{}}{\mathbf{atom}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{atomic}\mathbf{}\mathbf{mass}\mathbf{}\mathbf{of}\mathbf{}\mathbf{atom}}{\mathbf{total}\mathbf{}\mathbf{molar}\mathbf{}\mathbf{mass}\mathbf{}\mathbf{of}\mathbf{}\mathbf{compound}}{\mathbf{x}}{\mathbf{100}}}$

**Step 1**. Determine the molar mass of Cd(CH_{3})_{2}

**Step 2**. Divide the atomic mass of Cd over the molar mass of Cd(CH_{3})_{2}
