Cyclohexane Experiment

Satisfactory Essays
The density of our unknown object was 5.9(g/mL). However, the identified metal, zinc, has a theoretical density of 7.14(g/mL). This cause us to have -17.3% as our percent experimental error. Some likely causes of this was either that there were fingerprints still on the metal because of constant use, so there is bound to be some other substance on the metal. Or there were still a significant amount of air bubbles in the graduated cylinder which made our measurement inaccurate. Our density for the unknown liquid was .779(g/mL). The actual density of the liquid, cyclohexane, is .792(g/mL). Thus our percent experimental error is only -.64%. The reason for such a small percent error compared to the percent error of the metal, is most likely because
