Three hundred gallons of a mixture containing 75.0 wt% ethanoland 25% water (mixture specific gravity = 0.877)and a quantity of a40.0 wt% ethanol - 60% water mixture (SG = 0.952) are blended toproduce a mixture containing 60.0 wt% ethanol. The object ofthis problem is to determine V40, the required volume ofthe 40% mixture. Calculate V40 and do a degree-of-freedom analysis.
