What is the volume of one mole of ping pong balls?

Answer 1

Slice one ping pong ball in half.

Fill up the half of the ping pong ball with water.

Empty the water from the ping pong ball into a measuring cup.

Measure the amount of water in mL and multiply it by 2, ( there are two halves ).

Answer 2

I worked it out, and found that one mole of ping pong balls would cover the United States to a depth of 4208 km. This may be wrong though.

Answer 3

Use a balance or a set of scales
