The relative number of atoms of elements, ‘X’ and ‘Y’ in a compound is 0.250.25 and 0.5.0.5. The empirical formula of compound is.

A

XY

B

X2YX_{2}Y

C

XY2XY_{2}

D

X2Y2X_{2}Y_{2}

Answer

XY2XY_{2}

Explanation

Solution

(3) : Re;ative no. of moles of ‘x’ = 0.25 and ‘Y’ = 0.50.5

Mole ratio of ‘X’= 0.25/0.25=10.25/0.25 = 1

Mole ratio of ‘Y’= 0.5/0.25 = 2

Empirical formula = XY2XY_{2}
