Answer

Explanation:

Step1: Calculate moles of NaCl

$n=\frac{m}{M}$, where $m = 87.75\ g$ and $M=58.44\ g/mol$. So $n=\frac{87.75}{58.44}\ mol\approx1.50\ mol$.

Step2: Convert volume to liters

$V = 500\ mL=0.5\ L$.

Step3: Calculate molarity

$Molarity=\frac{n}{V}$, substituting $n = 1.50\ mol$ and $V = 0.5\ L$, we get $Molarity=\frac{1.50}{0.5}=3.00\ M$.

Answer:

3.00 M
