If you had a stock of 1.5 M sodium chloride solution and you needed to make 1 liter of 0.5 M sodium chloride , how would you make it? Show by picture , calcs and a sentence.

Expert Solution

Initial Final

M1 = 1.5M M2 = 0.5M

V1 = V2 = 1L

For dilution M1V1 = M2V2

V1= M2V2/M1 = 0.5 x 1/1.5 = 0.333 L

Volume of water added = 1 - 0.33 = 0.67 L
