The boiling point of a solution of 5 g of sulphur in 100 g of carbon disulphide is 0.474°C above that of pure
solvent. Determine the molecular formula of sulphur in this solvent. The boiling point of pure carbon disulphide
is 47°C and its heat of vaporisation is 84 calories per gram.
Answer: 246 g
Formula used for Elevation in boiling point :
= change in boiling point
= boiling point constant
m = molality
