Determine the density of CO₂ gas at 278 K and 1.00 bar.

Question

Quizplus · Accepted Answer

To determine the density of gas, we can use the ideal gas law which is PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant, and T is the temperature. We can rearrange this equation to solve for density (d = nM/V where M is the molar mass), which gives us d = PM/RT. Since we are given P and T, we need to find the molar mass of CO₂ which is 60.07 g/mol. Substituting the values into the equation, we get d = (1.00 bar) * (60.07 g/mol) / ((0.0831 L bar/mol K) * 278 K) = 1.90 g/L. Therefore, the best choice is C.
