Step-by-step explanation:
The density of a substance is defined as its mass per unit volume. In this problem, we are given the volume and the mass of the aluminum block, so we can calculate its density as follows:
Density = Mass / Volume
Substituting the given values, we get:
Density = 85.7 g / 28.0 mL
Simplifying this expression, we get:
Density = 3.06 g/mL
Therefore, the density of the aluminum block is 3.06 g/mL
