Lab Report Conclusion

end In this experiment, we measured the mass of 4 hit manses oxygen, carbon dioxide, helium, and lab gas. We took a Ziplock bag, and turned into a non-stretchy balloon, and filled with each gas and measured the unmixed mass then calculated the actual mass, then find a ratio between the mass of oxygen and the other gasses. We tried to march on the pressure about the alike each time so our calculations would be more than accurate. We give out that the heaviest was carbon dioxide, and the lightest was helium.In fact, helium and lab gas had a density below 0. Anyways, it turned out that our apparent great deal were very different from our actual mass calculations for example oxygens apparent mass was 28. 33g but its actual mass was 4. 10g. We also found the ratios, and after collecting class data, our carbon dioxide ratio was 1. 39/1g, our helium ratio was . 21/1g, and our lab gas ratio was . 59/1g. then(prenominal) we had to come up with two hypotheses to figure out why virtuos o gas is heavier (denser) than another?Well, we came up with hypothesis 1 The different pinch mass hypothesis, and hypothesis 2 The more molecules in the same ledger hypothesis. After having a class discussion, turns out that hypothesis one is more reliable due to Avogadros hypothesis if two gasses at the same temperature and equal volume contain equal amount of molecules. So agree to the statement above, the carbon dioxide molecules must be 1. 39x bigger than an oxygen molecule, a helium molecule must be . 21x bigger, and . 59x bigger than an oxygen molecule.
