Liquid benzene and liquid n-hexane are blended to form a stream flowing at a rate of 700 lb_m/hr. The blended stream has a density of 0.850g/mL. Estimate the mass and volumetric flow rates of the two components in American Engineering Units. What assumptions did you have to make? (specific gravity (SG) benzene 0.879, SG n-hexane 0.659, molecular weight (MW) benzene 78.11 g/mol, MW n-hexane 86.17 g/mol)
