Answer 1

Hi there,

Welcom to brainly family

♤Given:

▪X Atomic mass = 50

▪Y atomic mass = 16

▪Percentage of Y = 32%

▪Percentage of X = 68%

☆Step 1 find number of moles for each element

▪nX = 68÷50 = 1.36 mol

▪nY = 32÷16 = 2

☆Step 2 find mole ratio by divid both element on the lowest no of moles

▪X=1

▪Y=1.5 approximately

☆Step 3 correction the fraction by multiple ×2

◇The formula is X2Y3
