When 10 .6 g of a non volatile substance is dissolved in 750 g of ether, its boiling point is raised 0 .266 o C . The molecular weight of the substance is (Given: Molal boiling point constant for ether is 2 .0 o C kg/mol ) Report your answer by rounding it up to nearest whole number.

Correct answer

106

Step-by-step solution

Δ T b = i × K b × m 0.226 = 1 × 2.0 × 10.6 M 0.75 M = 2 × 10.6 0.266 × 0.75 = 106.26
