Draw and label the given stream and derive expression

Draw and label the given stream and derive expression for the indicated quantities in terms of labeled variables. the solution of part (a )is given as an illustration. A continuous stream contains 40.0moles% benzene and the balance toluene. Write expressions for the molar mass flow rate of benzene, nb(mol C6H6/s and mb (kg C6H6/s), in terms of the total molar flow rate of the stream, n (mol/s). The feed to a batch process contains equimolar quantities of nitrogen and methane. Write an expression for the kilogram of nitrogen in terms of the total moles n(mol) of the mixture. A stream containing ethane, propane and butane has a mass flow rate of 100.0g/s. Write an expression for the molar flow rate of ethane, nE (lb-mole C2H6/h), in terms of the mass fraction of this species, xE. A continuous stream of humid air contains water vapor and dry air, the latter containing approximately 21 mole% O2 and 79% N2. Write expression for the molar flow rate of O2 and for the mole fraction of H2O and O2 in the gas in terms of n1 (lb-mole H2O/s) and n2 (lb-mole dry air/s). The product from batch reactor contains NO,NO2, and N2O4. The mole fraction of NO is 0.400. write an expression for the gram-moles of N2O4 in terms of n (mol mixture) and yNO2 (mol NO2/mol)
