Question

Quizplus · Accepted Answer

The density of a gas can be calculated using the ideal gas law rearranged to find density: $ \text{Density} = \frac{PM}{RT} $. For chlorine gas (Cl2), M = 70.9 g/mol, P = 1.01 atm, T = 54.1 °C = 327.25 K, and R = 0.0821 L·atm/mol·K. Plugging these values in gives a density of approximately 2.67 g/L.
