Molarity of 1m aqueous NaOH solution [density of the solution is 1.02 g/ml]: A 1 M B 1.02 M C 1.2 M D 0.98 M Hard Solution Verified by Toppr Correct option is D) Solve any question of Solutions with:- Patterns of problems > Was this answer helpful? It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. We could assume that the solvent volume does not differ from the solution volume, but that is a lie so let's use the density of #"2.13 g/cm"^3# of #"NaOH"# at #25^@ "C"# to find out its volume contribution. So the moles of solute are therefore equal to the molarity of a solution multiplied by the volume in liters.
