Question 2 A graduated cylinder contains 9.73 mL of water. When a metal ball with a mass of 28.3 g is dropped (carefully!) into the graduated cylinder the water level rises to 12.90 mL of water. Which metal is the ball made from? A Mg (1.74 g/cm) B) Zn (7.14 g/cm) Ag (10.5 g/cm) D Cu (8.94 g/cm3)

A student is trying to determine some information about a metal sphere. He weighs a piece of metal sphere and it weighs 8.25g. When a student places it into a graduated cylinder containing water, the liquid levels rises from 6.25 mL to 10.47 mL. Part 1: What is the density of the metal sphere? Part 2: what is the radius of the metal sphere in mm?
