State Gay Lussac's lw related to pressure annd temperature of a gas. 3.2g of sulphur when vaporised, the sulphur vapour occupies a volume of 280.2 mL at STP. Determine the molecular formula of sulphur vapour under this condition. (S=32).

Text Solution

Verified by Experts

Second part: 280.2 mL of sulphur has a weight of 3.2 g at STP.
22400 mL of sulphur has a weight of 255.8 g at STP.
let, the molecular formula of sulphur be `S_(n)`.
So, `nxx32=255.8" or, "n=7.9~~8`
molecular formula of sulphur is `S_(8)`.
