Q = What is the molarity of this solution?
A = Sodium hydroxide has a molecular weight of 40.
NaOH
Sodium Na 23
Oxygen  0 16
Hydrogen H  1
Total = 40
Therefore a 1 molar solution of sodium hydroxide contains 40g/L of NaOH.
A 10% solution (w/v) would be 10g per 100ml or 100g per litre.
A 40% solution (w/v) is therefore 400g /L
So a 40% solution NaOH is 10 molar .
