Q.The boiling point of a solution of $0.1050 \text{ g}$ of a substance in $15.84 \text{ g}$ of ether was found to be $0.1^{\circ}C$ higher than that of pure ether. What is the molecular weight of the substance? ( $K_b \text{ for ether} = 2.16 \text{ K kg mol}^{-1}$ )

143.5 \text{ g/mol}

160.2 \text{ g/mol}

135.4 \text{ g/mol}

150.0 \text{ g/mol}

The correct solution involves applying the fundamental concept to derive the final value step by step...
