relationship b/w molarity,molality and densitym=1000M/1000d-M(mm)where m=molality           M=molarity           d=density           mm=molecular mass

if density of solution = d g/cc

molarity = M

molality = m

molar mass of solute = M0 

 

Lets take 1000ml of the solution, then

mass of solution = 1000d

moles of solute = M

mass of solute = MM0

mass of solvent = (1000d - MM0) grams

 

molality = m = 1000M / ( 1000d - MM0)
