0.75 g platinichloride of monoacid base ...

0.75 g platinichloride of monoacid base on ignition gave 0.245 g platinum. The molecular mass of the base is :

A

`75.0`

B

`93.0`

C

100

D

`80.0`

Text Solution

Verified by Experts

The correct Answer is:
B
If E = Eq.wt.of base
W = weight of platinichloride
w = weight of platinum, then
`(W)/(2E+410)=(omega)/(195)`,
`(0.75)/(2E+410)=(0.245)/(195)rArr E = 93.5`
