A solution of `Al_(2)(So_(4))_(3){d=1.253 gm//ml}` contain `22%` salt

1.	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 isA. `0.805M,0.825m`B. `0.825M,0.805m`C. `4.83M,4.83m`D. `4.83M,48.3m`
Answer» Correct Answer - A `"Molarity"=(%xx10xxd)/("gram molecular mass")` `=(22xx10xx1.253)/(324)=0.806M` `"Molality"=(22xx1000)/(342(100-22))=0.825m`
