A solution contains `75 mg NaCl` per `mL`. To what extent must it be diluted to give a solution of concentration `15 mg NaCl` per `mL` of solution.

Text Solution

Verified by Experts

The concentration is reduced to `1//5th`, without any change in the number of g of solute, hence the volume must incrase five fold. Dilute it to 5.0 times its former volume.
