You are given
the mass of aluminum block which is 40.5 grams and its volume at 15 milliliters.
You are required to find the density of the aluminum block in grams per
milliliters. You need to know that density is equal to mass over volume. Let us
denote D as our density, V our volume and M as our mass. So,
D = M/V
D = (40.5
grams) / (15 milliliters)
D = 27/10 or
2.7 grams per milliliters or 2.7g/mL
