In Section 184.108.40.206, the laboratory manual instructs you to “weigh out sufﬁcient solid [antacid tablet] to prepare 100 mL of solution at approximately 0.01 M in Ca 2+ ”. As instructed in Section 2.6.4 of the laboratory manual, you observe the calcium content reported on the antacid label and ﬁnd it to be “500 mg of calcium carbonate per tablet”. As instructed in Section 220.127.116.11, you then weigh the antacid tablet and ﬁnd the weight of the tablet to be 1309.9 mg. How much of the antacid tablet should you weight out to ultimately produce a 0.01 M in Ca 2+ solution, following the instructions in Section 18.104.22.168 to 22.214.171.124 of the laboratory manual? weight of ground antacid tablet = ____________________ mg Cornell University Chemistry 3000 — Fall 2009 J.
