2.75 g of mgo(s) is added to 70.0 ml of 2.4 mol/l hno3(Aq) is the concentration that results from the solution acidic or basic? What is the concentration of the ion that is responsible for the character of the solution. What is the pH ?
The Attempt at a Solution
First I found the mols of mgo and the mols of Hno3.
( convert g to mol for Mgo and multiplied the concentration by vol for HNo3)
Since they are not in a 1:1 ratio as seen by the balanced chemical equation I took the one with the greater mol(0.06822) which would be HNo3 and multiplied it by 2(molar ratio)
I then used this mol and divided it by the vol of the solution to get 1.95mol/l
However the book is saying .46.. What did I do wrong?
