The boiling point of pure acetone is 56....

The boiling point of pure acetone is 56.38^(@)C`. When 0.707 g of a compound is dissolved in 10 g of acetone there is elevation to `56.88^(@)C` in b.p What is the mol.wt. of the comound ?
`(K_(b)" of acetone"=1.72 K kg mole^(-1))`

Text Solution

Verified by Experts

`DeltaT_(b)=K_(b)xxm`
`rArr (56.88-56.38)=1.72xx(0.707)/(M_(B))cc(100)/(10)`
`:. M_(B)=243.2`
