`0.607g` of a silver salt of tribasic organic acid was quantitatively reduced to `0.37g` of pure Ag. What is the molecular mass of the acid ?

A

207

B

210

C

531

D

324

Text Solution

Verified by Experts

The correct Answer is:
2
Moles of `Ag_(3)A=("Moles of Ag")/(3)=(0.607)/(M)=(0.37)/(108)xx(1)/(3)`
`rArr " "M=531`
`:. " " mol. wt. `of `H_(2)A=mol. wt. ` of `Ag_(3)A-3xxAt. wt. ` of `Ag+3xxAt. wt. `of `H=210`
