Physical Properties

John fills a graduated cylinder with 50 mL of water. He then drops a 6 g key into the graduated cylinder. The water level inside the graduated cylinder rose to 53 mL as shown below.

If Density = Mass / Volume, determine the density of the key.

• 12 g/mL

• 2 g/mL

• 0.3 g/mL

• 3 g/mL
