Question

x gm A atom on combinng with Y atom of B from 5 moleculenof a compound contaning A and B find the molecular weight of compounds formed atomic weight of B=M

Answer 1

Answer:

Explanation:

As this information is not given here , WE ARE CONSIDERING THAT ALL AMOUNT OF SUBSTANCE A REACTS WITH GIVEN ATOMS OF B TO FORM COMPOUND CONTAINING A AND B.

NOW, TOTAL MASS OF A REACTED= Xgm

TOTAL MASS OF B REACTED = Y x M gm (no. of atoms x atomic weight)

total mass of reactans = X + YM gm

BY LAW OF CONSERVATION OF MASS, TOTAL MASS OF REACTANT IS EQUAL TO TOTAL MASS OF THE PRODUCTS .

THERE FORE MASS OF 5 MOLECULES OF FORMED COMPOUND = X + YM

THEREFORE MASS OF 1 MOLECULE OF GIVEN COMPOUND FORMED = (X + YM)/5............
