In the lab procedure, you are instructed to dissolve the Potassium hydrogen phthalate, KHP, in 100 mL of water. Will the amount of water used to dissolve the KHP affect the lab results? Explain.

I'm not sure what the lab procedure is. Will there be less KHP in let's say 200 ml (assuming the complete 200 ml is added to the reaction)?
No, the same amount is in, but won't the concentration change?

Yes concentration will change, but that is irrelevant if the complete solution is used in the reaction. I'll give an example in the next post.
it's a titration reaction
Suppose you want to add 1 cup of bleach to a load of laundry. You dilute 1 cup in 1 gallon for load 1. For load 2 you dilute 1 cup (of bleach) in 4 gallons, the concentration is less but you still have 1 cup. Concentration will affect, if you take out 10ml of solution, then yes the 2nd solution will have less bleach in the 10ml.
If it's a titration reaction you will know the molarity of the solution. It may take more solution to reach titration, but at your titration point, you'll be able to determine the amount of solute (KHP) based on molarity.
