Consider a continuous flow stream in a process which contains a mixture of benzene (b), toluene (t), xylenes (x), and 1,2-dichlorobenzene (d). the volumetric flow rate for the stream is 250 ml/min. the composition is 20% b by mass and 30% t by moles. there are three times as many moles of x as there are moles of d. assume the density of mixture is 0.97 g/ml and molar masses of each component are as follows: mb = 78.11 g/mol; mt = 92.14 g/mol; mx = 106.16 g/mol; md = 147.01 g/mol. (maintain 4 significant figures for all calculations). a) what is the stream's total molar flow rate (mol/min)? [ans: 2.440 mol/min] b) what are the mole fractions of each component in the stream? c) what is the weight fraction of (x) in the stream?

The mass has escaped into a gas which you can not see so the law stays true.

The answer is 323 g.
