Question

A solution containing 4.2 g of an organic compound in 50 g of acetone shows an elevation of boiling point by 1.8 K . Determine the molar mass of organic compound [Kb of acetone= 1.71 K oh mol-1]

Answer 1

use the formula deltatb eqauls to kb ×m

Explanation:

1.8=1.71×m

where mis molality

and molality =no of moles of solute/mass of solvent inkg
