The boiling point of Chloroform was raised by 0.325K when 5.141 × 10⁻⁴ kg of a non-volatile solute was dissolved in 35 × 10⁻³ kg of Chloroform. Calculate the molar mass of the solute?
(molal boiling point elevation constant for chloroform is 3.9 K kg mol⁻¹)

1. (a) 0.215 kg mol⁻¹
2. (b) 0.176 kg mol⁻¹
3. (c) 0.195 kg mol⁻¹
4. (d) 0.151 kg mol⁻¹
