When 3.2 g of S is vaporised @ 450°C and 723 mm pressure, the vapour occupies a volume of 780 cm3 what is the molecular formula of S in the conditions ?Pls explain​

Answer»

From ideal GAS equation, pV=wMRT ∴ M=3.2×0.0821×760×1000×723723×780=256 ∵ 32 g of sulphur has 1 atom of S. ∴ MOLECULAR formula=S8Explanation:
