What volume of a 6.0 M NaOH solution would you need to prepare 250.0 milliliters of a 3.0 M NaOH solution?

Answer 1

250 milliliters = 0.25 L;

To make a 3.0 M NaOH solution from 6.0 M NaOH, you need equal parts of water and NaOH solution

You need 0.25 Liters of the solution, so you need 1/2 * 0.25 = 125 milliliters 6.0 M NaOH, and 125 milliliters water
