A 250cm^3 solution of NaOH was prepared. 25.0cm^3 of this solution required 28.2cm^3 of 0.100moldm^3 HCl for neutralisation. Calculate what mass of NaOH was dissolved to make up the original 250cm^3 of solution.?? Please I need help with this.

1. Find the number of moles of a HCl in the question.
2. Write out a full equation.
3. Use molar ratios to obtain the correct number of moles of NaOH.
Sorry and thank you for the help, I had already calculated the solutions for HCl. I just did not know what to do from there on. Next time I will remember.
