    Here you'll need to use the mol, concentration, volume triangle to work out how much of each substance you need. It also depends on what volume of stock solution you want.

    So let's say you want 500 ml of 1M stock solution.

    So you know both the volume and concentration you want which will allow you to work out the mols of NaOH.

    For these calculations it's best to use dm3 as the units for volume. So 500 ml = 0.5 dm3

    As mols = conc x volume

    The mols of NaOH you'll need are 1 x 0.5 = 0.5.

    And you know how to convert mols of a substance to the mass you need to weigh out right?

    And so when you work out how much NaOH you need you'd dissolve that amount in 500 mL water for example.
