Calculate the mass of `Na_(2)CO_(3)` required to prepare 250 ml of 0.5 N solution.

Text Solution

Verified by Experts

Normality of required solution = 0.5 N
Volume of required solution = 250 ml
Equivalent wt.of.`Na_(2)CO_(3)=106/2=53`
Normality (N) = `omega/(GEW)xx1000/(V(ml))`
wt. of solute = `NxxGEWxx(V(ml))/1000`
`0.5xx53xx250/1000=53/8=6.62g`.
