The density of a gas can be calculated using the ideal gas law rearranged to find density: $ \text{density} = \frac{PM}{RT} $. Here, P = 1.35 atm, M (molar mass of NO) = 30.01 g/mol, R = 0.0821 L·atm/mol·K, and T = 29.8°C = 302.95 K. Plugging in these values gives a density of approximately 1.63 g/L.
