Answer

Answer:

C. 60.66%

Explanation:

Step1: Find molar mass of Na

The molar mass of Na (sodium) is approximately 22.99 g/mol.

Step2: Find molar mass of Cl

The molar mass of Cl (chlorine) is approximately 35.45 g/mol.

Step3: Calculate molar mass of NaCl

The molar mass of NaCl = molar mass of Na + molar mass of Cl = 22.99+35.45 = 58.44 g/mol.

Step4: Calculate percent - mass of Cl in NaCl

Using the formula $%Cl=\frac{\text{molar mass of Cl}}{\text{molar mass of NaCl}}\times100=\frac{35.45}{58.44}\times100\approx60.66%$.
