Problem 2 - Root-Finding: Equations of State It is proposed to use a steel tank to store carbon dioxide at 300K. The tank is 3.0m3 in volume (V) and the maximum pressure (p) it can safely withstand is 150atm. a) Using Python, determine the maximum number of moles (n) of CO2 that can be stored in the tank using the three equations of state given below (each uses the molar volume Vm=V). Use the Modified Secant method to solve the problem with a tolerance of 0.01 mol. For Beattie-Bridgeman, you will also use the Newton-Raphson method with the same tolerance. Report the maximum n for each equation of state and method (4 total). b) Assuming that the Beattie-Bridgeman equation is the most accurate, what is the percent error in the calculated number of moles n using the other two equations of state?
