what is the relationship between molarity and molality
Molarity=(no of moles of solute)/(volume of solution in litrs)
while molality=(moles of solute)/(wt of solvent in kg)
the above two have a relationship as-
molality= Molarity/(density of solution-Molarity*molecular wt of solute)
m = M / (ρ - M x mw A)
apply this relation to solve numericals when density of solution is given...
Molarity is defined as number of moles divided by the volume (in liters).
whereas
Molality is defined as the number of moles divided by the mass of the solution (in kg).
Please approve by clicking "Yes" below!!
molarity = no. of moles ofsolute/vol of soln. in litre
molality = no. of moles of solute/ wt. of solvent.
if density of solvent is given we can find out relation between molality and morality..
