Question:
The exit gas from an alcohol fermenter consists of an air-C02 mixture containing 10 mol% C02 that is to be absorbed in a 5.0-N solution of triethanolamine, containing 0.04 mol of carbon dioxide per mole of amine solution. If the column operates isothermally at 25oC, if the exit liquid contains 78.4% of the C02 in the feed gas to the absorber, and if absorption is carried out in a six-theoretical-plate column, calculate:(a) Moles of amine solution required per mole of feed gas.(b) Exit gas composition.Y = moles C02/mole air; X = moles C02/mole aminesolution

I consider myself to have excellent interpersonal and assessment skills with strong teaching presentation verbal and written communication
I love tutoring. I love doing it. I find it intrinsically satisfying to see the light come on in a student's eyes.
My first math lesson that I taught was when I was 5. My neighbor, still in diapers, kept skipping 4 when counting from 1 to 10. I worked with him until he could get all 10 numbers in a row, and match them up with his fingers.
My students drastically improve under my tutelage, generally seeing a two grade level improvement (F to C, C to A, for example), and all of them get a much clearer understanding!
I am committed to helping my students get the top grades no matter the cost. I will take extra hours with you, repeat myself a thousand times if I have to and guide you to the best of my ability until you understand the concept that I'm teaching you.
