Statement - I : One molar aqueous solution (d=1gm/cc) has always higher concentration than one molal.
Statement - II : The molality of a solution does not depends on temperature whereas molarity depends

consider 1 molal sol. of Glucose

  nsolute = 1  ,   Ws = 1(180) = 180g

  Wo =1000g

1 molal solution  means  1 mole solute present in 1000g of solvent

1 Molar solution  of Glucose:

                        ns =1 ,  Ws = 1(180) =180g

                        Vsol = 1000ml , dsol. =1g/cc

                         Wsol.  = 1000g, Wo = (1000-180) = 820g

1M sol. means 1 mole of solute in 820g of solvent

By comparing 1M & 1m sol. of Glucose,

1M sol. is more concentrated than 1m sol.

(ii) $\mathrm{molality}\propto \frac{1}{{\mathrm{W}}_{\mathrm{solvent}}}$

Wt. of substance is independent of Temperature

$\mathrm{Molarity}\propto \frac{1}{{\mathrm{V}}_{\mathrm{solution}}}$

Vol. depends on Temp. and Molarity depends on Temp.
