Calculate how much KOH you will need to weigh out to make 250 mL of a 0.2M KOH solution. How much potassium hydrogen phthalate (molar mass 204.23 g/mol) do you need to weigh out if you want to use 20.00 mL of your standard 0.2000 M KOH solution to titrate the potassium hydrogen phthalate sample? Note: potassium hydrogen phthalate has ONE hydrogen that reacts with KOH. We often use KHP as our "simplified formula" for potassium hydrogen phthalate rather than...
