Question

A compound AB completely decomposes into A and B on heating. 50 g of AB, on strong heating, gave 40 g of A. How much quantity of AB should be decomposed by heating to obtain 2.5 g of B? How much quantity of A will be produced in the process?

Answer 1

Explanation:

Since according to law of conversion of mass, 50g of AB produces 40g of A and 10g of B, so when we heat 12.5g of Ab, we will get its 1/5

th
