    Molarity of liquid \[HCl\] if density of solution is 1.17 g/cc

    A)  36.5                      

    B)         18.25   

    C)         32.05                   

    D)         42.10

    Correct Answer: C

    Solution :

    Density \[=1.17\,g/cc\] \[=1170\,g/L\]                 Molarity of solution \[\text{= }\frac{\text{Strength}\,\text{in}\,\text{g/L}}{\text{mol}\text{.wt}}\] \[=\frac{1170}{36.5}\,\text{M}\] \[=32.05\,\text{M}\]
