How are you feeling about your ability to apply the density formula to calculate density?
This is pretty easy for me
As long as I have the formula in front of me I think I'll be alright
Numbers and math scare me so I have no confidence even if I'm doing it right
I can't follow what we're doing so I should probably watch the Edpuzzle and Notes and maybe come for extra help

If we find a gold nugget with mass = 77.2g and Volume = 4 cm^2 (4 ml). How do we know is real gold?
We multiply mass x volume, then compare our results with the table of densities
If density = mass/volume, if we insert our values into the formula we get the density of gold. (19.3 g/cm^2)
we get the density by dividing volume over mass and compare with a density table
