air (79%mole nitrogen and 21mole%oxygen)is separated into two product streams.the separator operates at a steady state.

air (79%mole nitrogen and 21mole%oxygen)is separated into two product streams.the separator operates at a steady state.one product stream is 98mole%oxygen, and it contains 80% of the oxygen in the air fed into the column.the other product is mostly nitrogen.calculate the quantity of air required(ton/day)to produce 1ton/yr of the oxygen product.calculate the mole%nitrogen in the second stream.
