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.

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.

e) **Calculate the molarity of excess reactant** remaining in the Erlenmeyer Flask.

This table represents a chemical experiment measuring the mass of precipitate formed by adding different net volumes of silver nitrate (AgNO₃) to a solution. The table is divided into three columns:

1. **Net Volume of AgNO₃ Added (mL):** Indicates the volume of silver nitrate added to the solution.
2. **Total Volume (mL):** Represents the total volume of the mixture after adding silver nitrate.
3. **Mass of Precipitate (g):** Shows the resulting mass of solid precipitate formed in the reaction.

This data can help illustrate the relationship between the volume of reactant added and the amount of product formed.
