25cm3 of a solution of NaOH required 28cm3 of 1.0mol/dm3 H2SO4 to neutralise it:
a) write an equation for the reaction.
b) how many molesof H2SO4 were needed?
c) how many moles of NaOH were thus nuetralised?

2NaOH + H2SO4 ==> Na2SO4 + 2H2O
I think for (b) you means how many mols H2SO4 were used. All of ot was meeded.
mols H2SO4 = M x L = ?
(c) Using the coefficients in the balanced equation, convert mols H2SO4 you had to mols NaOH neutralized.
(d) usually these problems want you to calculate the M of the NaOH.
That's M NaOH = mols NaOH/L NaOH
