Perform the following calculations using only the data from when you added a net volume of 30.00 mL of dilute AgNO3 to the standard Na3AsO4 solution. Again, only perform these calculations for the 30.00 mL point. The rest of the calculations will be done in Excel. a) Calculate the initial millimoles of each Reactant that was added to the Erlenmeyer Flask.

concentrate of AgNO3 is 0.02

Perform the following calculations using only the data from when you added a net volume of 30.00
mL of dilute AgNO3 to the standard Na3AsO4 solution. Again, only perform these calculations for
the 30.00 mL point. The rest of the calculations will be done in Excel.
a) Calculate the initial millimoles of each Reactant that was added to the Erlenmeyer Flask.
Hint: the standard Na3AsO4 was 0.01000 M and you calculated the concentration of dilute
AgNO3 solution in Part A Step 4.
b) Calculate the millimoles of precipitate formed. Use the mass of precipitate and the molar
mass of the solid.
c) Calculate the change in millimoles for each reactant. Use your answer from calculation b)
and the stoichiometric ratios in the balanced chemical equation.
d) Calculate the millimoles of excess reactant that remain in the Erlenmeyer Flask.
Calculate the molarity of excess reactant remaining in the Erlenmeyer Flask.
