Gyou are an engineer at a plant that produces a certain candy that has popping reaction when eaten. to do this, your plant uses carbon dioxide, co2, (a= 0.396 pa m6, b= 42.69 x 10-6 m3/mol) and needs to bring the co2 gas to a pressure of 4 x 106 pa to create this effect. using the ideal gas law, calculate themoles of co2 needed to achieve this pressure in a 1-liter chamber (0.001 m3) at 280 degrees fahrenheit (411k). use this n in the van der waals equation to get a better estimate of the pressure with that much gas. do the calculations and print your results (with units! ) to the screen in an informative message. in your evaluate step, also answer the following question: is the amount of gas you calculated using the ideal gas law likely to be sufficient in the candy making process? why or why not?

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
