The molarity of orthophosphoric acid having purity of 70% by weight and specific gravity 1.54 would be

A

11 M

B

22 M

C

33 M

D

44 M

Text Solution

Verified by Experts

The correct Answer is:
A
70% by weight 70 gm `H_(3)PO_(4) rarr 100` gm solution/sample
`V=W/d=100/1.54" "M=(70xx1000)/(98xx100//1.54)=11M`
