Question

you need to make 50.00 ml of 0.00100 M NaOH solution. Calculate the volume of 0.0500 M NaOH solution and the volume of H20 to make proper dilution?

Answer 1

Hi!

Answer: 1ml of NaOH and 49 ml of Water

Concentration of NaOH to make: 0.001 M ( C1 )

Volume of NaOH to make: 50 ml ( V1 )

Concentration of NaOH in stock: 0.05 M ( C2 )

Volume of stock to use: V2

Using the formula C1 V1 = C2 V2 which is the standard formula for determining the dilutions to acquire a specified volume and concentration, we get:

0.001 M x 50 ml = 0.05 M x V2

V2 = 1 ml

So using 1ml of 0.05 M NaOH and 49 ml of Water

Hope this helps
