A Compound of X and Y Has the Empirical Formula Xy2. Its Vapor Density is Equal to Its Empirical Formula Weight. Determine Its Molecular Formula - Chemistry
A compound of X and Y has the empirical formula XY2. Its vapor density is equal to its empirical formula weight. Determine its molecular formula.
Empirical formula = XY2
Vapor density = Empirical formula weight
Molecular formula =?
Molecular weight = n(Empirical formula weight)
= 2 x V.D.
n(Empirical formula weight) = 2 x V.D.
Since Vapour density Empirical formula weight
n = 2
Molecular formula = 2(Empirical formula)
Molecular formula = X2Y4
Concept: Deduction of Simple (Empirical) and Molecular Formula from the Percentage Composition of a Compound
