1. Calculate the volume of 6.0M NaOH needed to make 0.50 L of 0.15M NaOH.
2. Determine the mass of H₂C2O4 2H₂O(s) needed to make 250. mL of 0.10M H₂C₂O4.
3. If 32.96 mL of a NaOH solution are required to titrate 25.00 mL of 0.1042M H₂C2O4 to
the end point, what is the molarity of the sodium hydroxide?
4. If 24.92 mL of the NaOH solution from question 3 are required to titrate 0.2794 g of an
unknown diprotic (n = 2) acid, what is its molar mass?
