0.4857 g of KHP was dissolved in water and titrated with a solution NaOH of unknown Molarity. A volume of 20.35 mL of NaOH solution was required to reach the endpoint. Two more runs with 0.4449 g and 0.4701 g of KHP required 19.04 and 19.73 mL of the NaOH respectively.

a)Calculate the mL of NaOH/g KHP for each run.

b)Find the mean, standard deviation, and CV

c) The fourth run with 0.4501 g of KHP needed 18.89 mL of NaOH, find the new mean, standard deviation, and CV

d)What is the molarity of the NaOH solution?
