A piece of magnesium weighs 27.5 g, and occupies 13.7 cm3. What is the density of the piece of metal?

2.01 g/cm3 density equals mass over volume. so 27.3g/13.7cm^3 = 2.01 g/cm^3 hope that helps!!

I always remember that "density breaks hearts" -- If you look at the equation, you can picture a heart with a horizontal line through it (see attached MSPaint scribble!). D=M/V
