Answer:
Initial Volume: 20 mL
Final Volume: 32 mL
Volume of the rock: 12mL
Explanation:
From the image we see that the initial volume of water is 20 mL, and after the rock is put into the flask, the final volume is 32 mL. From this we conclude that the volume of the rock must be 32mL-20mL = 12 mL.
Thus we have:
Initial Volume: 20 mL
Final Volume: 32 mL
Volume of the rock: 12mL.
