Explanation
The molarity of liquid A in liquid B can be determined by considering the density of the solution. Density is, mass Density = Volume For a binary solution of two liquids A and B the molality of a solution is determined as, 0 1000 m d M = 1000 mM x x Where M is the molarity, m is molality, 0 M is the molar mass of solute and d is the density of the solution. Molarity is calculated as, no.of moles of solute M = Volume in L .so, it is defined in terms of volume .molality is calculated as no.of moles of solute m = weight of solvent in kg .So it is defined in terms of mass. Hence, the assertio
