What are the 3 steps in determining the density of an object?
1. Determine the mass in grams.
2. Determine the volume in cm3.
3. Divide the mass by the volume
(500g)/(100cm3)=5g/(cm3)

An element's atomic number is the number of ______ in an atom.
The number of protons in an atom equals it's atomic number.

True or False: Relative density of an object can only be determined for a solid in water.
False, liquids, solids, and gases all have different relative densities.
ex. Maple syrup is denser than water. A sponge is less dense than oil. Helium is less dense than oxygen.

What is the difference between mass and weight?
Mass is the amount of matter is in something and weight is gravity acting upon an object's mass.
