Part A: Basic Laboratory Operations Density of a Solid TRIAL 1 TRIAL 2 Mass of solid (g) 19.761 g 19.763 g Volume of water (cm³) 75.0 cm^3 75.0 cm^3 Volume of water and solid (cm³) 78.0 cm^3 78.0 cm ^3 Volume of solid (cm³) 3.0 cm^3 3.0 cm^3 Density of solid (g/cm³) 7.0 g / cm^3 7.0 g / cm^3 Average density of solid (g/cm³) 7.0 g / cm^3 Identity of solid Zinc metal [Density = 7.133 g/cm^3] 1. Density of Zinc: Consider the data and results from the density of zinc determination. Now focus on the average absolute error associated with the calculated average density of zinc. Which measurement contributes the most relative error to this value? Given that measurement and its associated absolute error, is the calculated average absolute error reasonable and why? What aspect of the experiment limited the measurements the most?
