1. If a student needed to calculate the density of irregularly shaped metal beads give a brief explanation of the best way to do so with a graduated cylinder, water and a balance.2. Using the method described above, calculate the density of a quantity of copper beads. The initial volume of the graduated cylinder with water was 35 ml, the volume of the water plus the beads 40.7 ml and the mass of the beads 50.217 g. What is the density of the beads and what is the percent error.
