2. It requires 27.5 mL of a NaOH solution to titrate 0.214 g of H2C2O4 (MM = 90.0). What is the molarity of the NaOH solution? It requires 42.5 mL of a NaOH solution to titrate 25.0 mL of a 0.192 M HCl solution. If 32.4 mL of the NaOH solution is required to titrate a solution containing 0.410 g of an unknown acid, what is the molar mass of the monoprotic unknown acid? It requires 17.5 mL of Sr(OH)2 solution to titrate a solution containing 0.613 g KHP (MM 204.2 g/mol). If 31.4 mL of the Sr(OH)2 solution is required to titrate 7.04 g of an impure HC2H3O2 (MM 60.0) solution, what is the % of HC2H3O2 in the solution? A 0.104 M NaOH solution is used to titrate a solution containing 0.124 g KHP (MM = 204.2) and 0.140 g H2C2O4 (MM 90.0). What volume (in mL) of NaOH is required?
