If a P-20 micropipettor is set at “110,” what volume of water will this measure? How much should that water weigh? If a P-1000 micropipettor is set at “035”, what volume of water will this measure? How much should that water weigh?

A stock solution was diluted in two steps. In a first step, 0.5 ml was diluted with 9.6 mL buffer. In a second step, 0.5 mL from the first step was diluted with 9.6 mL of buffer. The concentration of the mixture of the second step was determined to be 0.24 mg/mL. What was the concentration of the stock solution?

Based on information provided, could you please answer only question B? (Please show your work) Na2S203 Flask 1 Flask 2 Flask 3 Initial 14.15 28.04 Final 27.07 43.85 31.06 49.87 KBr03 Flask 1 Flask 2 Flask 3 Initial 40 35.20 41.2 Final 60 45.22 51.2 Concentration of Na2S203: 0.0898M Concentration of KBr03: 0.020M Concentration of NH3OhHCI: 0.02M Calculations a) For each of the three sets of data calculate the number of moles of KBr03 initially delivered into each flask, considering the volume of KBr03 delivered and its concentration. From the result of the titration of unreacted KBr03 with Na2S203, find the number of moles of KBr03 remaining in the solution at the end of the 10-minute reaction period. The difference between these two values gives the number of moles of KBr03 which reacted with the hydroxylammonium ion. Calculate the average of the three values for the moles of KBr03 which reacted. b) Find the number of moles of electrons which must have been transferred between Br03-…
