Lithium has an atomic radius of 0.152 nm, a BCC crystal structure, and an atomic weight of 6.941 g/mol. Compute its theoretical density (in g/cm³). Show all your steps and calculations. If you are going to determine the density of a 3 cm x 3 cm by 2 cm block of lithium using a caliper with a resolution of 0.05 mm and a balance of with a resolution of 0.1 g. Which device contributes to a larger percent error? Assume that the error in the measurements is only due to the minimum resolution. Clearly show your analysis and conclusion. Make any necessary assumptions; however, clearly indicate them.
