Question

How can we convert 250 ml semimolar solution to decimolar solution?

Answer 1

Answer:

Volume of deci normal Solution= 50 ml. Concentration of decinormal Solution=0.1N Volume of centi normal Solution= V concentration of centinormal Solution=0.01. So V x 0.01 = 50 x 0.1. Therefore V = 50 x 0.1/0.01= 500 ml. So the amount of water to be added to 50 ml.of deci normal Solution. = (500- 50)= 450 ml.
