Answer to Question #79621 in General Chemistry for Amanda Mcmahan

Question

A volume of 20.0 mL of a 0.780 M HNO3 solution is titrated with 0.120 M KOH. Calculate the volume of KOH required to reach the equivalence point.
Express your answer to three significant figures, and include the appropriate units.

Answer 1

Answer:
Calculate number of moles of HNO3 = 0.780 moles/L x 0.020 L =0.0156 moles
At the equivalence point number of moles of HNO3 is equal to number of moles of KOH.
Volume of KOH = 0.0156 moles / 0.120 moles/L = 0.130 L of KOH
