A solution of $5.6 g$ nonvolatile solute in $50 g$ solvent has elevation in boiling point $1.75 K$ . What is the molar mass of solute $(K_{b} = 3 K kg mol^{- 1})$ ?

Options:

Answer:

Solution:

$M_{2} = \frac{1000 K _{b} W _{2}}{Δ T _{b} W _{1}} = \frac{1000 \times 3 \times 5.6}{1.75 \times 50} = 192 g mol^{- 1}$
