93.0 mL of 0.150 M magnesium hydroxide is added to 57.0 ML of 0.4 nitric acid. Magnesium nitrate and waer are formed. What is the concentration of the magnesium nitrate after the reaction?

The balanced reaction is Mg(OH)2 + 2 HNO3 ---> Mg(NO3)2 + 2 H2O. If you calculate the number of moles of each reactant, you'll find that you have 0.0140 moles of magnesium hydroxide and 0.0228 moles of nitric acid, so nitric acid is your limiting reagent. The largest number of moles of magnesium nitrate you can form is 0.0114 moles, which would be in a total of 150 ml of solution, or a concentration of 0.076 M.
