A graduated cylinder has a mass of 50 g when empty. When 30 mL of water is added, the graduated cylinder has a mass of 120 g. If a rock is added to the graduated cylinder, the water level rises to 75 mL and the total mass is now 250 g.

Answer

Question: What is the mass of the rock?

Answer: The initial mass of the cylinder with water is 120 g. The total mass with the rock is 250 g. Therefore, the mass of the rock is 250 g - 120 g = 130 g.

Question: What is the volume of the rock?

Answer: The water level rises from 30 mL to 75 mL, indicating the volume of the rock is 75 mL - 30 mL = 45 mL.
