Three hundred gallons of a mixture containing 75.0 wt% ethanol (ethyl alcohol) and 25% water (mixture specific gravity = 0.877) and a quantity of a 40.0 wt% ethanol—60% water mixture (SG = 0.952) are blended to produce a mixture containing 60.0 wt% ethanol. The object of this problem is to determine V, the required volume of the 40% mixture.

(a) Draw and label a flowchart of the mixing process and do the degree-of-freedom analysis.

(b) Calculate V40.
