Question

What volume of water should be added in 200ml of 1.5M of KOH solution to obtain 0.005M solution of it?​

Answer 1

Answer:

60 L

Explanation:

The dilution foormula is

M'V' = M"V"

M' is the former molarity and V' is the volume at M'

M" is the molarity after dilution and V" is the volume at M"

Substituting the values, 1.5 × 200 = 0.005 × V"

So, V" = (1.5 × 200)/ 0.005

V" = 60000 mL

= 60 L
