Answer:
Assuming the % mass of solution is expressed in w/w and the density of solution ~ 1.
Volume of the NaOH solution : 150 g or 150 mL [V1]
Intial concentration of NaOH solution : 20 % w/w [C1]
Final concentration of NaOH : 6% w/w [C2]
Final volume of solution : ? [V2]
Using the renowned formula :
V1 . C1 = V2 . C2
150 . 20 = V2 . 6
V2 = 500 mL
Hence,
The amount of water must be added is (500mL - 150mL) = 350mL to obtain the concentration of NaOH reduced to 6%.
