Two liquids 'A' and 'B' form an ideal solution. At 300 K, the vapour pressure of a solution containing 1 mole of 'A' and 3 moles of 'B' is 550 mm Hg. At the same temperature, if one more mole of 'B' is added to the solution, the vapour pressure of solution increases to 560 mm Hg. Then the ratio of vapour pressures of A and B in their pure state is

Elements A and B form two non-volatile compounds (AB and AB ). When 1 g of AB is added to 20 g of C H (molar mass =78 gmol ) the freezing point of C H is lowered by 2.3 K. When 1 g of AB is added to 20 g of C H , the freezing point of C H was lowered by 1.3 K. The atomic masses of A and B are respectively (K (C H )=5.1 K kg mol )
