A researcher is using 7.20 x 1023 molecules of chlorine gas (Cl2) in an experiment. How many grams of chlorine is the researcher using? Remember to include units (abbreviated appropriately) and the substance in your answer. Round your answer to the nearest 0.01.

A 15.5 g sample of sodium carbonate is added to a solution of acetic acid weighing 19.7 g. The two substances react, releasing carbon dioxide gas to the atmosphere. After reaction, the contents of the reaction vessel weigh 28.7 g. What is the mass of carbon dioxide given off during the reaction?

In the opening scenes of the movie Raiders of the Lost Ark, Indiana Jones tries to remove a gold idol from a booby-trapped pedestal. He replaces the idol with a bag of sand of approximately equal volume. (Density of gold = 19.32 g/cm3; density of sand 2 g/cm3.) a. Did he have a reasonable chance of not activating the mass-sensitive booby trap? b. In a later scene, he and an unscrupulous guide play catch with the idol. Assume that the volume of the idol is about 1.0 L. If it were solid gold, what mass would the idol have? Is playing catch with it plausible?
