Answer

Explanation:

Step1: Calculate moles of NaCl

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

Step2: Convert volume to liters

$V = 500\ mL=0.500\ L$.

Step3: Calculate molarity

$Molarity=\frac{n}{V}=\frac{1.50\ mol}{0.500\ L}=3.00\ M$.

Answer:

D. 3.00 M
