Asubstance has a mass of 360 g and a volume of 7.5 cm3. what is its density? a. 2700 g/cm3 c. 480 g/cm3 b. 270 g/cm3 d. 48 g/cm3 select the best answer from the choices provided a b c d

Density can be calculated by:

where D is the density, M is the mass, and V is the volume.  In this case we have m = 360g, V=7.5 cm^3  by plugging in these values we have:

C.) 480 g/cm^3

Pro-tip: Look at the units, they sometimes tell you what to do.  In this case all of your answers have grams over cm^3 this means grams divided by cm^3.  Even if you do not know the equation you can infer what it is by knowing what units you have vs. what units you should end up with.
