A sealed container has a volume of 0.020 m³ and contains 15.0 g of molecular nitrogen (N₂), which has a molecular mass of 28.0 u. The gas is at 525 K. What is the absolute pressure of the nitrogen gas?

Question

Using the ideal gas law, PV = nRT, where n = mass/molar mass = 15.0 g / 28.0 g/mol = 0.536 mol, R = 8.314 J/(mol·K), T = 525 K, and V = 0.020 m³, we find P = (0.536 mol)(8.314 J/(mol·K))(525 K) / 0.020 m³ = 1.2 × 10⁵ Pa.
