Titration Calculations

Quite a tough one for today…

13.8g of a solid monoprotic acid was dissolved in water and made up to 250 cm3. 25.0 cm3 portions of this were titrated against 0.25 mol dm-3 sodium hydroxide, requiring 23.5 cm3 sodium hydroxide solution. Calculate the Mr of the acid.

Hint…

work out the concentration in g per dm3 and write everything in a table with units to make it clear
