Calculate the mass percent of the different elements present in sodium sulphate `(Na_(2)SO_(4))`.

Text Solution

Verified by Experts

Given compound is sodium sulphate `(Na_(2)SO_(4))`
Molecular weight of the compound = 2(23)+ 1(32)+4(16)
= 46 + 32 +64
=142
Step -I :
Mass percent of Na
142 gms of `Na_(2)SO_(4) to 46` gms of Na
100 gms of `Na_(2)SO_(4) to ?`
`(100xx46)/(142)=32.39%`
Step-II
Mass percent of .S.
142 gms of `Na_(2)SO_(4)to 32` gms of .S.
100 gms of `Na_(2)SO_(4)to ? `
`(100xx32)/(142)=22.53%`
Step -III
Mass percent of .0.
142 gms of `Na_(2)SO_(4)to 64` gms of oxygen
100 gms of `Na_(2)SO_(4)to ?`
`(100xx64)/(142)=45.07%`
:. Mass percents of Na,S,O are 32,39,22,53,45.07.
