Question
When sulfuric acid reacts with ammonia solution an ammonium salt and water are produced. Calculate the volume of 3mol/dm3 of acid required to react exactly with 25ml of a 2.5mol/dm3 of ammonia solution.

H2SO4 + 2NH3 ==> (NH4)2SO4
How many mols NH3 do you have? That is M x L = mols = ?
How many mols H2SO4 will it take to exactly react with the NH3? That will be 1/2 mols NH3 = ?
M H2SO4 = mols/dm^3
You know M and mols, solve for dm^3.
