1. 25.0 moles/h of a mixture containing nitrogen and oxygen (90% N2 on a molar basis) is combined with 37 moles/h of a second nitrogen oxygen mixture (20% N2 on a molar basis). Determine the composition of the output stream. P= 1 atm and is constant. T = 30C and is constant. Output: Mole Fraction N2: ________ Mole Fraction O2: ___________
