The three hundred gallons of a mixture containing 75.0wt% ethanol (ethyl alcohol) and 25% water (mixture specific gravity=0.877) and a quantity of a 40.0wt% ethanol-60%water mixture (SG=0.952) are blended to produce a mixture containing 60.0wt% ethanol. The object of this problem is to determine V40 , the required volume of the 40% mixture. (a) Draw and label a flowchart of the mixing process and do the degree- of-freedom analysis, and calculate V40.
