What is the percent composition of chlorine in C2H2Cl2? Solve to the correct number of significant figures.
oksian1 [2.3K]

Answer:

\%Cl=73.13\%

Explanation:

Hello.

In this case, we can compute the percent composition of chlorine as shown below:

\%Cl=\frac{2*m_{Cl}}{M_{C_2H_2Cl_2}}

Whereas the atomic mass of chlorine is 35.45 g/mol and the molar mass of C₂H₂Cl₂ is 96.95 g/mol, thus, the percent composition turns out:

\%Cl=\frac{2*35.45g/mol}{96.95g/mol}*100\%\\\\\%Cl=73.13\%

Best regards.
