Question

25mL of water is measured into a graduated cylinder. A 6g fish tank pebble he dropped into the water and makes the water line rise to 27mL. What is the mass,volume, and density if the pebble?

Answer 1

Step-by-step explanation:

The volume of the pebble is 27 mL - 25 mL = 2 mL.

The density of the pebble is its mass divided by its volume, so the mass of the pebble is 6 g / 2 mL = 3 g/mL.

The density of the pebble is therefore 3 g/mL.
