A three-liter tank contains two gram-moles of nitrogen at 150.8°C. Estimate the tank pressure using the ideal gas equation of state and then using the virial equation 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: T. = 126.2 K, p. = 33.5 atm, and = 0.040¹2.

A three-liter tank contains two gram-moles of nitrogen at 150.8°C. Estimate the tank
pressure using the ideal gas equation of state and then using the virial equation 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: T₁ = 126.2 K, pc = 33.5 atm, and = 0.040¹2.
