Two elements A and B which form 015 moles of A2B and AB3 typ

Question

Two elements A and B which form 0.15 moles of A₂B and AB₃ type compounds. If both A₂B and AB₃ weigh equally, then the atomic weight of A is _____________...

Accepted Answer

Let atomic weight of A = x

and atomic weight of B = y

Molar mass of A₂B = 2x + y

and molar mass of AB₃ = x + 3y

Now, weight of 0.15 moles of A₂B = (2x + y) 0.15

and weight of 0.15 moles of AB₃ = (x + 3y) 0.15
