The term mole first used by Ostwald in 1...

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:

A

`941`

B

`1882`

C

`470.5`

D

`1411.5`

Text Solution

Verified by Experts

The correct Answer is:
B
`3.4gS equiv100 g mol.wt.`of substance
`2xx32gS=(100xx2xx32)/(3.4)`
`18882 g` i.e., `mol.wt.`
