Why doesn't water and oil mix together?

The density of oil is less than water, therefore it floats on top of the water

100

What is the formula for density?

Density = mass/ volume

100

What is the smallest part of an element?

atom

There is 400 mL of water in a graduated cylinder. We add a marble to the graduated cylinder and the water rises to 410 mL. The mass of the marble is 20g. What is the density of the marble?

(Hint: This is a 2 step problem. Think about the way you find volume of an irregular shaped object)

2g/mL  or 2g/cm3
