Solution
The mass of sulphur atom is 32 amu per atom. Same is the mass of sulphide ion as weight of gained electrons is negligible. So, mass of sulphide ion is also 32.
One sulphide ion has -2 relative charge i.e. 32 amu sulphide ion corresponds to -2 relative charge.
Number of sulphide ions in 96 amu= 96/32= 3 sulphide ions.
Therefore total relative charge= 2*3= 6
The exact charge is 6×e= 9.6×10^(-19).
