Assuming that CO2 obeys perfect gas law, calculate the density of CO2 (in kg/m3) at 263°C and 2 atm ?
Correct answer: B. 2
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
Using the ideal-gas relation for density, ρ = PM/RT, with P = 2 atm, M = 44 kg/kmol, and T = 536 K gives approximately 2 kg/m3. Hence option b is the closest value.
