Class average for a 80 and 120 drop count was recorded to be 0.041+/- 0.005 mL/drop. If a graduated cylinder is not available there is another way of adding more of the solution. The disposable pipet can transfer 0.5mL of the solution to the chemical reaction. When comparing a 10mL graduated cylinder, a 100mL beaker, and a 50mL graduated cylinder, the most precision peace of glass wear would be the 10 mL graduated cylinder with the true volume of water (calculated), class average, and uncertainties being 9.7896 +/- 0.05mL. The 50mL graduated cylinder comes in second place with a true volume of water(calculated), class average, and uncertainties being 50.0001 +/- 0.22mL. The third peace of glassware coming in as the least accurate would be the 100 mL beaker with a true volume of water(calculated), class average, and uncertainties being 59.9999 +/- 0.82mL.
Metal bar D(lead) has a identity of 11.36, in the experimental density +/- uncertainty bar D is 11.2+/- 0.6 g/mL. The theoretical density information was founded in General Chemistry Laboratory Manual for CSU Bakersfield, CHEM 211, 3rd ed. Buschhaus, M. 2015. Each experimental identification described was strongly supported by there experimental densities +/- uncertainty and by only being off by 0.06. Both results come out in range of what is being searched for. The bars still have a little more play room with their densities and will still be in
