Two beakers of capacity 500 mL were taken. One of these beakers, labelled as "A" was filled with 400 mL water whereas the beaker labelled "B" was filled with 400 mL of 2M solution of NaCl. At the same temperature both the beakers ware placed in containers os same material and same capacity as shown in figure.

Two beakers of capcatity 500 mL were taken one of these beakers labelled as "A" was filled with 400 mL water whereas the beaker labelled "B" was filled with 400 mL of 2 M solution of NaCl. At the same temperature both the beakers were placed in close containers of same material and same capacity as shown in the figure given below: At a given temperature, whihc of the following statement is correct about the vapour pressure of pure water and that of NaCl solution.

One of the two vessels of same capacity is filled with oxygen and other is filled with helium of same mass. Both gasess are at same temperature. The ratio of pressure of these gases is
