Amixture of methane and air is capable of being ignited only if the mole percent of methane is between 5% and 15%. a mixture containing 9.00 mole% methane in air flowing at a rate of 700.0 kg/h is to be diluted with pure air to reduce the methane concentration to the lower flammability limit. calculate the required flow rate of air in mol/h and the percent by mass of oxygen in the product gas. (note: air may be taken to consist of 21.0 mole% o2 and 79.0 mole% n2 and hence to have an average molecular weight of 29.0).
