10% w/v or 10% w/w they are the same if water is the solvent, so 100g/l NaOH is 2.5 molar
If 1 litre contains 2.5 moles, then 1/2.5 lites contain 1 mole of NaOH - 400mls

A 10% solution of NaCl would have 100g of NaCl in 900 mL of water. The molarity would be 100/(40 x0.900) = about 2.78 M
1000/2.78 =360 mL to contain one mole of NaOH.
These numbers are approximations as no densities are given to make more accurate calculations. These estimates will be pretty close to actual numbers.
