densities of both an unknown solid and an unknown liquid with available equipment. Observations: Solid : Trial # 1 10.392 Trial # 2 10.389 Trial # 3 10.388 Trial # 1 3.75 Trial # 2 3.75 Trial # 3 3.75 Mass (avg)= (10.392g + 10.389g + 10.388g)/3 = 10.390g Volume (avg)= (3.75ml + 3.75ml + 3.75 ml)/3 = 3.75 ml Density = Mass/Volume Density = 10.390g/3.75ml = 2.77 g/ml The Density of Aluminum is 2.7 Therefore we conclude that our unknown solid is Aluminum. This is consistent with its color and reflectivity. Percent error = (Accepted – Mean)/ Accepted Percent error= (2.7-2.77)/2.7 = .26 We had a fairly high degree of precision in our experiment, especially in measuring volume where the value was found to be 3.75 each time. Our masses were also very similar and averaged no more than .02 from any single trial. Liquid:
