22.5-5. steam stripping and number of trays. a relatively nonvolatile hydrocarbon oil contains 4.0 mol % propane and is being stripped by direct superheated steam in a stripping tray tower to reduce the propane content to 0.2%. the temperature is held constant at 422 k by internal heating in the tower at 2.026 × 105 pa pressure. a total of 11.42 kg mol of direct steam is used for 300 kg mol of total entering liquid. the vapor–liquid equilibria can be represented by y = 25x, where y is mole fraction propane in the steam and x is mole fraction propane in the oil. steam can be considered as an inert gas and will not condense. plot the operating and equilibrium lines and determine the number of theoretical trays needed. ans. 5.6 theoretical trays (stepping down from the tower top)

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments,solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
