Answer:
0.441 M KHP
Step-by-step explanation:
KHP has a molar mass of 204.22 g/mol. It is Not actually KHP, it has its own longer formula C8H5KO4, Potassium hydrogen phthalate.
To find the molarity we will simply do moles/L
moles = 1.802 g x (1 mol KHP / 204.22 g) = 0.008824 mol KHP
The volume needs to be in L so divide by 1000, 20.0/10000 = 0.0200 L
Molarity = moles / L = 0.008824 moles / 0.0200 L = 0.441 M = [KHP]
