0.75 g platinic chloride of a mono-acidic base on ignition gave 0.245 g platinum. The molar mass of the base is:

A

`75.0`

B

`93.5`

C

100

D

`80.0`

Text Solution

Verified by Experts

The correct Answer is:
B
`("Mass of" B_2H_2Pt Cl_6)/(2B+410)=("Mass of Pt")/(195)`
`:. (0.75)/(2B+410)= (0.245)/195 " " :. B = 93.5`
Eq. mass of base=93.5, since it is monoacidic. `:.` Molar mass of base `= 93.5 xx 1 = 93.5`
