Determine the volume (mL): how much of our diluted NaOH is needed for determining the mass of KHP to use when standardizating. To neutralize 0.7 M NaOH. Save the rest of your NaOH for the Vinegar titration.

I got 10 mL of 7 M NaOH required for 100 mL of 0.7 M NaOH. I need help with how much of that NaOH I need to find the mass of KHP.
