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. Calculate n = 15.0 g / 28.0 g/mol = 0.536 mol. Use R = 8.314 J/(mol·K) and T = 525 K. Solve for P: P = (nRT)/V = (0.536 mol × 8.314 J/(mol·K) × 525 K) / 0.020 m³ = 1.2 × 10⁵ Pa.
