Volume NaOH added M Molarity NAOH
Homework Answers
You are determining the molar mass of molecule KHC8H4O4
And to calculate the molar mass of this unknown compound you have to first determine the Molarity of KHC8H4O4
And in quantitative analysis/titration process - to determine the concentration of unknown compound the Molarity of one compound is known which is going to be filled in burette. That means the standard solution of NaOh is prepared in lab whose Molarity should be known to you. So please discuss with your labmates to check the recorded data of concentration of NaOH.
And the volume of NaOh can be calculated by calculating = final concentration - initial concentration
Trial 1 = 55.44 - 4.8 = 50.64 mL
Trial 2 = 7.50 - 0.0 = 7.50 mL
Trial 3 = 17.90 - 0.00 = 17.90 mL
Trial 4 = 7.35 - 0.5049 = 6.8451 mL
