1. A three-liter tank contains two gram-moles of nitrogen at − 150.8o C. Estimate the tank pressure using the ideal gas equation of state and then using the Virialequation of state truncated after the second term. Taking the second estimate to be correct, calculate the percentage error that results from the use of the ideal gas equation at the system conditions. Data for nitrogen: Tc = 126.2 K, pc = 33.5 atm, and ω = 0.04012.

- The vapor pressure of water at 40.0C is 7.34103N/m2. Using the ideal gas law, calculate the density of water vapor in g/m3 that creates a partial pressure equal to this vapor pressure. The result should be the same as the saturation vapor density at that temperature (51.1g/m3).arrow_forwardThe law of atmospheres states that the number density of molecules in the atmosphere depends on height y above sea level according to nV(y)=n0en0gy/kaT where n0 is the number density at sea level (where y = 0).
