Suppose you add a solution of calcium hydroxide to a solution of
sodium carbonate and a precipitate forms. You measure the total
amount of the precipitate (in g) as a function of time. At time 0,
20.0 s, 40.0 s and 60.0 s you get a cumulative weight of 0.00 g,
4.82 g, 6.33 g and 8.49 g of the precipitate, respectively. What is
the average rate of reaction between 40 and 60 seconds in mol/s?
