Question

The equivalent weight of a solute $X$ is $20$. When $10gm$ of solute is present in $2$ liters of solution, its normality is:

• A. $0.2N$
• B. $5N$
• C. $0.5N$
• D. $0.25N$

Answer 1

The correct option is D $0.25N$

Given, Equivalent weight= $20$ Given weight $W=10$

$V=2L=2000ml$

So, Normality= $\frac{W}{M}\times \frac{1000}{V}=\frac{10}{20}\times \frac{1000}{2000}$

$\Rightarrow N=\frac{1}{4}=0.25N$ .
