What is the density of carbon dioxide gas at -25.2$\degree$C and 98.0 kPa?

Question

Quizplus · Accepted Answer

To find the density of CO2, use the ideal gas law: $ PV = nRT $. Rearrange to find density: $ \rho = \frac{PM}{RT} $. Convert temperature to Kelvin (247.95 K) and pressure to atm (0.967 atm). Use molar mass of CO2 (44.01 g/mol) and R = 0.0821 L·atm/mol·K. Calculate density: $ \rho = \frac{(0.967 \, \text{atm})(44.01 \, \text{g/mol})}{(0.0821 \, \text{L·atm/mol·K})(247.95 \, \text{K})} \approx 2.09 \, \text{g/L} $.
