How do you find the volume when mass and density is gone?

Answer 1

You would need to measure the volume directly by making measurements using some kind of laboratory apparatus. You would use a graduated cylinder if it's a liquid. If it's a regular solid like a cube or rectangle, you could measure it's length, width, and height and calculate volume with a ruler or meter stick. If it's an irregular solid, you can find it's volume using an overflow by water displacement.

However, if you do not have the substance available to actually measure, it will be impossible to determine the volume using the density formula. You must have two of the variables in order to calculate the missing one.
