Additioonal Feat! Dexter and Mandark team up in order toprevent the asteroids from destroying Earth. They start thisplanet saving feat by weighing a gelatin capsule (0.117g) Next they add pieces of aluminum/zinc alloy to the capsuleand weigh the capsule and alloy (0.200 g). They weigh out an emptybeaker (112.600 g) and begin the experiement. After the reaction,they determine the mass of the beaker (with the displaced water) tobe 202.437 g. The temperature of the water was 22 Celsius and thebarometric pressure was 735.8 mm Hg.
How many moles of hydrogen gas are there? How many moles of hydrogen per gram of the sample?
