In a reaction, 25.0 grams of magnesium are added to a beaker containing 75.0 mL of 2.00 M nitric acid, HNO3. Which reactant is limiting? Which is in excess?

How many moles of Mg do you have? (25/23.5 ?)
how many moles of H do you have? (.075*2)
so is the nitric acid moles twice the Mg? If moles Nitric acid is >2*moles Mg, then Mg is limiting.

You have the equation in the problem.
