You haven't supplied enough information. Is that 10% w/w, 10% v/v, 10%w/v or 10% molar? You need to know how many g of NaOH there are in 1 litre of solution. Divide that by 40 and you have your answer.

A 10% solution of NaOH is 100g per litre (w/v). [10g per100ml]

A molar solution of NaOH is 40g per litre (w/v).

A 40% solution of NaOH is a molar solution.

THE MOLAR CONCENTRATION OF 10% NaOH IS:
2.5 mol per litre (being 100/40).

C = (N/A) / V

N is the number of molecules present in the volume. This is measured in litres. A is the Avogadro's number, 6.023 1023 and V is obviously volume.
Then find 10% of it.

I can't work it out for you, you need to give the volume of sodium hydroxide that you want to work out.
