Problem data: ν (amount of taken nitrogen substance) = 20 mol.
Reference values: according to the condition M (molar mass of nitrogen) = 0.028 kg / mol.
To determine the mass of taken nitrogen, we use the formula: ν = m / M, whence m = ν * M.
Let’s calculate: m = 20 * 0.028 = 0.56 kg.
Answer: 20 moles of nitrogen have a mass of 0.56 kg.
