The term mole first used by Ostwald in `1896` refers for the ratio of mass of a substance in `g` and its molecular weight. `1 "mole"` of a gaseous compound occupies `22.4 "litre"` at `NTP` and contains `6.023xx10^(23)` molecules of gas.
A substance contains `3.4%` sulphur. If it contains two molecules of sulphur per molecule the minium molecular weight of substance will be:
