The initial water volume in this container was 10.0 mL. When the key was submerged, 3 volumes of displaced water were collected: 0.7 mL, 0.8 mL, and 0.9 mL. What is the volume of the key?

Question

mL

Answer 1

To find the volume of the key, we need to subtract the volumes of the displaced water from the initial water volume.

Volume of key = Initial water volume - Volume of displaced water
= 10.0 mL - (0.7 mL + 0.8 mL + 0.9 mL)
= 10.0 mL - 2.4 mL
= 7.6 mL

Therefore, the volume of the key is 7.6 mL.
