Question

two elements x and y (atomic mass of x=75 and y=16) combine to give a compound having 76% of x . the formula of the compund is..

Answer 1

Component – X, Y rate – 76,

24 mass proportion - 76/75 = 1.01, 24/16 = 1.5

nuclear proportion - 1.01/1.01 = 1x 2 = 2, 1.5/1.01 = 1.48≈1.5 x 2 = 3.

So experimental recipe of compound = X₂Y₃.

For sub-atomic equation you need to give sub-atomic mass of the compound.
