Question

A graduated cylinder is filled to an initial volume of 20ml. A ball is dropped into the graduated cylinder. The final volume of the graduated cylinder is 29 ml. If the has a mass of 27 g. What is the density of the ball?

Answer 1

Hey there! I'm happy to help!

A graduated cylinder is basically a cylinder with little measurements on it.

If we drop the ball into the cylinder and the final volume in 29 instead of 20, this means that the ball has a volume of 9 mL as it took up 9mL of the water, pushing it up 9 mL.

Density is mass divided by volume. The ball has a mass of 27 g and a volume of 9mL. So, the density is 3 g/mL.

Have a wonderful day! :D
