After performing precipitation gravimetry, Asta placed the weighing form inside the crucible, heated it, cooled it down, and weighed the crucible with the weighing form and obtained a mass of 23.4120 g. Repeating this cycle continuously gave a mass of 23.2125 g, then 23.1136 g, then 23.1139 g. Which among these masses should he use for his calculations? a. 23.1139 g b. 23.4120 g c. 23.1136 g
