Question

An aqueous solution of NaCl contains 20% NaCl. The density of the solution is 1.16 g/ml. One litre of water of density 1g/ml is added to 1 litre of the solution. Determine the molality and molarity of the resulting solution.

Answer 1

Answer:

Molar solution means there are 3 moles of NaCl salt in 1 Liter. ... Mass of 1 litre of solution = 1.25 gms/ml * 1000 ml = 1, 250 gms. V = volume of water added to make the solution.
