JEE Main 2022 · 28 Jul · Shift 1, Chemistry question 81

In the given reaction,

X+Y+3Z⇌XYZ3\mathrm{X+Y+3Z\rightleftharpoons XYZ_3}

if one mole of each of X and Y with 0.05 mol of Z gives compound XYZ3\mathrm{XYZ_3}. (Given : Atomic masses of X, Y and Z are 10, 20 and 30 amu, respectively.) The yield of XYZ3\mathrm{XYZ_3} is ______ g. (Nearest integer)

Answer and worked solution

Official answer: 2

Z is limiting. 0.053\frac{0.05}3 mol of XYZ3\mathrm{XYZ_3}, with molar mass 10+20+90=12010+20+90=120: 2 g.

Answer: 2
