The volume of 5 grams of a substance is 2cm^2. Calculate the density. What might this substance be?

ρ=2.5⋅g⋅cm3

Explanation:

ρ=Mass/Volume=5⋅g2⋅cm3,

and thus typically it has the units g⋅mL−1 or g⋅cm−3.

Here, mass=5⋅g, and volume=2⋅m3.

Their quotient is the density as shown. And this could be any solid material (generally solids are denser than liquids). You will have to look up tables of densities for common materials.

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
