JEE Main 2022 · 27 Jun · Shift 1, Chemistry question 83

2 g of a non-volatile non-electrolyte solute is disolved in 200 g of two different solvents A and B whose ebullioscopic constants are in the ratio of 1 : 8. The elevation in boiling points of A and B are in the ratio xy\dfrac xy (x:y)(x:y). The value of yy is ______. (Nearest Integer)

Answer and worked solution

Official answer: 8

Same molality. ΔTb∝Kb\Delta T_b\propto K_b, so the ratio is 1:81:8 and y=8y=8.

Answer: 8
