Calculate the percentage of platinum in ...

Calculate the percentage of platinum in ammonium chloroplatinate `(NH_(4))_(2)PtCI_(6)` (Give your answer correct to the nearest whole number).
(Atomic masses: H = 1, N = 14, CI = 35.5, Pt = 195)

Text Solution

Verified by Experts

Molecular mass of `(NH_(4))_(2)PtCl_(6)=2N+8H+Pt+6Cl`
`=(2xx14+(8xx1)+195+(6xx35.5)=444`
Mass percentage of platium `=("Atomic mass of Pt")/("Molecular mass of ammonium chloroplatinate") = xx 100`
`=(195)/(444)xx100=43.9=44`
