| Initial data: m (mass of aluminum) = 5.4 kg.
Reference values: M (molar mass of aluminum) = 27 g / mol (0.027 kg / mol).
The amount of substance in a piece of aluminum can be defined as the ratio of physical mass to molar: ν = m / M.
Let’s make a calculation: ν = 5.4 / 0.027 = 200 mol.
Answer: 5.4 kg of aluminum contains 200 mol of a substance.
