Verified Answer :

It's (grams-of-Cl/total-grams)(100), so (35.45g/58.44g)(100) = 60.66% Cl. Hope this helps!

Answer:

\(\% Cl=61.65\%\)

Explanation:

Hello,

In this case, chlorine's percent composition is given by the shown below formula:

\(\% Cl=\frac{n_{Cl}m_{Cl}}{M_{NaCl}}*100\%\)

Whereas \(n_{Cl}\) accounts for the number of chlorine atoms into the NaCl, \(m_{Cl}\) for chlorine's atomic mass and \(M_{NaCl}\) for sodium chloride's molar mass, therefore, the percent composition of chlorine turns out:

\(\% Cl=\frac{1*35.45}{58.45}*100\%=61.65\%\)

Best regards.
