Question

A solution contains $1.2046\times {10}^{24}$ hydrochloric acid molecules in one $d{m}^3$ of the solution. The strength of the solution is:

• A. $6N$
• B. $2N$
• C. $4N$
• D. $8N$

Answer 1

Answer: (B)

$2N$

Number of moles of $HCl$ =$\frac{1.2046\times {10}^{24}}{(6.023\times {10}^{23})}=2moles$

Normality = $Molarity\times valencyfactor$

Valency factor for HCl is 1

$\therefore Normality=2\times 1$

$\therefore Normality=2$\ N$

Hence, the correct option is $B$
