What is the definition of MASS? "Weight" is not an acceptable answer.
How much matter something is made up of.

300
What is the density of water? (correct answer must include a proper unit)
1g/mL
300
When would I use a cm3 as opposed to an mL?
When measuring the volume of a solid?

If the density of a diamond is 3.5 g/cm3 , what would be the mass of a diamond whose volume is .5 cm3?

1.75 g

What happens to your mass on a different planets?
Nothing - Mass does not change, weight does.
400
Which has a larger volume: a small, heavy rock or a fluffy, light cotton ball?
Volume is how much space something takes up: cotton ball.
400
Explain why the unit for density is g/cm3
You divide mass by volume so the density unit is the mass unit over the volume unit.
400
What are the two units we used for density?
g/mL and g/cm3

 A piece of wood that measures 3.0 cm by 6.0 cm by 4.0 cm has a mass of 80.0 grams. What is the density of the wood? Would the piece of wood float in water? 

1.11 g/cm3 it would sink

If the density of water is 1g/mL and I have 463mL of water, how many grams of water do I have?
463grams

If the density of maple syrup is 2g/mL, and I have 16 grams of syrup, what is the volume of my maple syrup?
.125 mL
500
What happens to the density as I add more mass? Answer must explain why.
It stays the same. More mass means more volume, and because I divide mass by volume to get density, density always stays the same.
500
Which is larger a cm^3 or an mL? Explain.
Neither - they are equal to each other.
