Question

An unknown "KHP" reacts with NaOH with a ONE to ONE stoichiometric ratio. If 10.00 mL of 2.0 M HCl reacts completely with a sample of KHP, calculate the number of moles of KHP in this sample.

Hint: Follow the steps

Step-1: Find the moles of NaOH in 10.00 mL = (2.0 mole / 1.0 L) X (1.0 L / 1000 mL) X (10.00 mL) = 0.02 moles of NaOH

Step-2: Consult the stoichiometric ratio between KHP and NaOH = 1:1, based on this, decide the number of moles of KHP in the sample

	1.	0.04
	2.	0.02
	3.	0.06
	4.	0.01
