Question

Two elements A & B combine to form two compound AB_2 and A_2B_3 - If molecular mass of AB_2 is 46 and that of A_2B_3is 76 then molecular mass of A_2B_5, will be​

Answer 1

Answer:

Let x and y be atomic masses of A and B respectively 

0.15= x+2y9.3 and 0.15 =2x+3y15.9

x+2y=62 and 2x +3y=106

y=18 and x=26
