Question

The normality of a solution that has $15g$ equivalents of solute dissolved in $750mL$ solution is .

• A. $15N$
• B. $75N$
• C. $20N$
• D. $0.2N$

Answer 1

The correct option is C $20N$

Recollect that,

Normality = $\frac{\text{Number of gram equivalenets of solute}}{\text{Volume of solution (in litres)}}$

= $\frac{15}{750\times {10}^{-3}}$ $(750mL\to 750\times {10}^{-3}L)=20N$
