I need the answer as soon as possible

Extracted text: H.W: Oxygen gas is flowing through a 10 m long circular pipe with a radius of 16 cm, The concentration of oxygen at the ends of the pipe are 30 kg/m and 10 kg/m. The diffusion constant of oxygen at 20 °C is 1.8 * 10$ m²/s. (a) Calculate the diffusion flow rate (b) How many kg of oxygen will flow through this pipe in 15 minutes? (c) Calculate the concentration gradient. (d) What is the concentration of oxygen 2 m away from the end of the pipe at high concentration? (e) How long will take 100 kg of oxygen to travel through this pipe?
