Question

A bead weighs 15 g, you place it in a graduated cylinder that has 20mL of water in it. After placing the bead in the cylinder, the water level is now at 30mL. What is its density?

Answer 1

I found: `rho=1.5g/(cm^3)`

Explanation:

Density `rho` is equal to `""mass"/"volume"`
so in our case the mass is `15g` while the volume should be: `30-20=10ml=10cm^3`

The density of the material of the bead should then be:
`rho=15/10=1.5g/(cm^3)`
