Question

In the given reaction, X + Y + 3 Z ⇄ XYZ 3 if one mole of each of X and Y with 0 . 05 mol of Z gives compound XYZ 3 . (Given : Atomic masses of X , Y and Z are 10,20 and 30 amu , respectively). The yield of XYZ 3 is____ g .

Z is present in least amount so, it will be limiting reagent and amount of product will depend on the amount of Z.
$X + Y + 3 Z \to {XYZ}_{3} initially 1 1 0.05 finally 1 - \frac{0.05}{3} 1 - \frac{0.05}{3} \frac{0.05}{3}$
$Molar mass of {XYZ}_{3} = 10 + 20 + 30 \times 3$ $= 120$
Mass $= number of moles \times molar mass = 120 \times \frac{0.05}{3}$
$= 2 gm$
