Problem- 1) The titration of a 20.0 mL sample of an H2SO4 solution of unknown concentration requires 22.87 mL of a 0.158 M KOH solution to reach the equivalence point. What is the concentration of the unknown H2SO4 solution (in molarity)?
2) Calculate the molarity of a solution made by adding 45.4 g of NaNO3 to a flask and dissolving it with water to create a total volume of 2.50 L.
Rewrite your answer from the stating and prove each step carefully.
