Question
Two elements A and B combine to form compound X and Y. For the fixed mass of A, masses of B combined for the compounds X and Y are in 3:7 ratio. If in compound X, 4 g of A combines with 12 g B, then in compound Y, 8 g of A will combine with …… g of B.
Options
A.24
B.56
C.28
D.8
Solution
In compound ‘Y’, 4 g of A will combine with 
= 28 g of B, and hence, 8 g of A will combine with 2 × 28 = 56 g of B. s
