Determination of Ideal Gas LawConstantJesse Fox22 December 2017Ideal Gas LawIntroduction: This lab explores and tests the relationship between pressure and thenumber of moles needed according to the ideal gas law. The objectives of this lab are
to determine the ideal gas law constant, use a catalyst in an oxidation-redux reaction,use the ideal gas law to determine the number of moles of gas that are generated in areaction.Materials:Bottle, 15-mLPlastic tubingYeast packetHydrogen Peroxide, 3%Graduated cylinder, 10-mLGraduated cylinder, 500mLBeaker, 250-mLWeight boatGraphing programTap waterActivity 1 -1.Record the current air temperature with the thermometer and record in DataTable 1.2.Fill 50-mL graduated cylinder completely with water.3.Fill 250-mL beaker completely with water.4.Attach the dropper top to one end of the clear tubing.5.Insert the opposite end of the tubing into the 50-mL graduated cylinder.6.Place thumb over opening of the 50-mL graduated cylinder and invert into thebeaker.7.Record the initial volume of gas in the graduated cylinder in Data Table 1. If nogas is present, the volume will be 0.8.Turn on the balance.9.Place a weigh boat on the balance and tare it.10.Weigh 0.1 gram of yeast onto the weigh boat.
