Calcium oxide neutralises acids such as nitric acid. A student neutralised 1.50g of CaO with 2.50mol dm^-3 nitric avid HNO3. The equation is shown below
CaO(s) + 2HNO3 (an) > Ca(NO3)2 (aq) + H2O (I)
1. How many miles if CaO were reacted?
2. Calculate the volume of 2.50mol dm^-3 HNO3 needed to exalcgu neutralise 2.50 g of CaO
For the first one I got 0.0267 mol and I never got the second

So far so good.
How many moles of nitric acid are required?
You have the concentration of the acid so use the equation
Conc = moles / vol
