The largest number of molecules is present in 3.8 g of water because water has the lowest molecular mass among the given substances, so the same mass contains more moles and hence more molecules.

One-liner

According to Raoult's law, the relative lowering of vapour pressure for a solution is equal to the mole fraction of the solute.
