Answer

Answer:

$4.5\ mol/L$

Explanation:

Step1: Calculate moles of HCl

$n=\frac{m}{M}=\frac{25\ g}{36.46\ g/mol}\approx 0.686\ mol$

Step2: Convert volume to liters

$V = 150\ mL\times\frac{1\ L}{1000\ mL}=0.15\ L$

Step3: Calculate molarity

$M=\frac{n}{V}=\frac{0.686\ mol}{0.15\ L}\approx 4.5\ mol/L$
