QUESTION 8

What is the molarity of HNO ₃ if 25.41 mL of 0.1013 M Ba(OH) ₂ are required to react with 70.43 mL of HNO ₃ solution according to the reaction below?
2 HNO ₃(aq) + Ba(OH) ₂(aq) → 2 H ₂O(l) + Ba(NO ₃) ₂(aq)

Key Concept:Stoichiometry in solutions. The proportional way that compounds react, e.g. aA + bB →cC + dD. This tells us that we can find the mol of one if we know the mol of another in the reaction. Using the proportional behavior described by the balanced reaction. If there are 5 mol of B. We would say the mol of A must be 5 mol B* (A mol A/b mol B). In solutions we can determine moles of each using n = M*V, where n = mol, M = molarity and V = volume.
