Two streams flow into a 500.0-gallon tank. the first stream is 10.0 wt % ethanol and 90.0 wt% hexane (mixture density is rho1 0.680 g/cm3) and the second is 90.0 wt% ethanol, 10.0 wt% hexane (mixture density rho2 0.780 g/cm3).

after the tank has been filled, which takes 22.0 minutes, an analysis of its contents determines that it is 65.0 wt% ethanol and 35.0 wt% hexane.

estimate the density of the final mixture and the mass and volumetric flow rates of the two feed streams.

mass flow rate of stream 1:

kg/min

volumetric flow rate of stream 1:

l/min

mass flow rate of stream 2:
