Two elements A and B form compounds having formula AB2 and AB4. When dissolved in 20 g of benzene (C_6H_6), 1 g of `AB_2` lowers the freezing point by 2.3 K whereas 1.0 g of `AB_4` 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.
