Two elements A and B form compounds having formula AB2 and AB4. When dissolved in 20 g of benzene $\left( C _6 H _6\right), 1 g$ of $AB _2$ lowers the freezing point by 2.3 K whereas 1.0 g of AB4 lowers it by 1.3 K. The molar depression constant for benzene is 5.1 K kg mol-1. Calculate atomic masses of A and B.
