A 160ft3-incubator requires an inert atmosphere composed of 70mol%1-pentene (C5H10) and the balanced is helium (He) in order to work efficiently. The operating incubator conditions are 120atm and 350F. Your supplier provides the options of cylinders to purchase the gas mixtures as in Table 1. Table 1: Cylinders for Gas Mixture Storage (a) Recommend suitable cylinder type(s) for your purchase since the supplier can only fulfil 50 cylinders per order. Given, number of cylinder = total mass of gas mixture/cylinder capacity (20 Marks) (b) Based on your answer in part (a), compare and choose the most cost effective cylinder if you can buy only one type
