A solution of `Al_(2)(So_(4))_(3){d=1.253 gm//ml}` contain `22%` salt by weight. The molarity , normality and molality of the solution is

A

0.805 M, 4.83 N,0.825 m

B

0.825 M, 48.3 N, 0.805 m

C

4.83 M, 4.83 N, 4.83 m

D

None

Text Solution

Verified by Experts

The correct Answer is:
A
Molality = `(%xx10xxd)/(GMM)=(22xx10xx1.253)/(342)=0.805M`
Normality = `(%xx10xxd)/(GEM)=(22xx10xx1.253)/(342//6)=4.83N`
Molality = `(22xx1000)/(342(100-22))=0.825m`.
