Matt R Results & Analysis Part 1: 1.) To determine the density and composition of a penny it must be first weighed on a scale. Find the average mass of multiple pennies from the same year. After weighing it find the volume by placing the pennies into a 50 ml beaker with 15 ml of water. Note the change in volume to obtain the volume of the pennies‚ obtain the average volume‚ and then calculate the density by dividing the mass of the penny by the volume. 2.) To keep measurements accurate and precise
