0.96g chloroplatinate of a diacid base when ingnited gave 0.32 g platinum. The molecular mass of the base is [AW of Pt = 195]

A

175

B

350

C

`87.5`

D

210

Text Solution

Verified by Experts

The correct Answer is:
A
`(W)/(ZE+410)=(omega)/(195)`
`(0.96)/(ZE+410)=(0.32)/(195)rArr E = (175)/(2)`
`MW=Z xx E` since it is diacidic base
`therefore MW = Z xx (175)/(2)=175`
