Q5 of 27 Page 47

500 mL of a 1M solution of common salt is taken.

If the solution is diluted with water to a volume of 2 L, what will be the molarity?

If the solution is diluted with water to a volume of 2 L, the molarity will be:


As number of moles = 0.5 (calculated in part a)


Volume in litres = 2L (given)


∴



Molarity = 0.25M


Thus, the molarity will be 0.25M
