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?
