What is the Maximum Theoretical Yield Ppt. (mol)?
a. What is the relative height of each of the precipitates? Assume that the tube with the least amount of precipitate has a relative height of 1. HINT: Divide each height by the smallest one.
b. What is the relative number of theoretical moles of product in each tube? Assume that the tube with the lowest theoretical yield has a relative yield of 1.
c. How do the relative heights and theoretical moles in the six tubes compare with one another? Why?
The Maximum Theoretical Yield Ppt. (mol) is the maximum amount of precipitate that can be formed in a reaction mixture, based on the stoichiometry of the reaction and the limiting reactant. In order to find the Maximum Theoretical Yield Ppt. (mol), refer to the provided data table and locate the column labeled "Maximum Theoretical Yield Ppt. (mol)".
In this particular table, the column is given as the fifth column from the left. Simply look under the corresponding tube number, and you will find the value for the Maximum Theoretical Yield Ppt. (mol) for each reaction mixture.
For example, in Tube 1, the Maximum Theoretical Yield Ppt. (mol) is given as 0.6 mol. Similarly, for Tube 2, the Maximum Theoretical Yield Ppt. (mol) is 1.3 mol.
To find the Maximum Theoretical Yield Ppt. (mol) for a specific tube number, locate the tube number in the leftmost column of the data table, and then look under the "Maximum Theoretical Yield Ppt. (mol)" column for that tube number.
