help with ACID questions please, not that strong in chemistry, can you show

me steps how to do this? It was found that 20.20 mL of an HNO3 solution are needed to react completely with 3.0 x 102 mL of an LiOH solution that has a pH of 12.05. What is the molarity of the HNO3 solution?

A solution was made by dissolving 0.8096 g Ba(OH)2 in water to give 0.2409 L final volume. What is the molar concentration of OH- in the solution, in M?

A solution was made by dissolving 0.6888 g Ba(OH)2 in water to give 0.1352 L final volume. What is the hydrogen ion concentration, in M?
