Q = What is the molarity of this solution?A = Sodium hydroxide has a molecular weight of 40.NaOHSodium Na 23Oxygen 0 16Hydrogen H 1Total = 40Therefore 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 /LSo a 40% solution NaOH is 10 molar .
