When a block of aluminum occupies a volume of 15.0 ml and weighs 40.5 grams, its density would be 2.7 gram / cm³
What is density?
It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.
Water has a density of 1 gram/cm3 at 4 degrees Celsius. Density is a physical characteristic that relies on a number of other variables, including temperature, pressure, and many more.
By using the above formula for density
ρ = mass / volume
As given in the problem a block of aluminum occupies a volume of 15.0 ml and weighs 40.5 g
As we know 1 ml = 1 cm³
15 ml = 15 cm³
density = 40.5/15
= 2.7 gram / cm³
Thus, the density of the aluminum block would be 2.7 gram / cm³
