Assertion :For  a  binary  solution  of  two  liquids,  A and  B,  with  the  knowledge  of  density  of  solution, molarity can be converted into molality. Reason: Molarity is defined in terms of volume and molality in terms of mass, and mass and volume are related by density.

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
