Answer the following question and explain why the answer is the answer. Rubbing alcohol sold in stores is aqueous 2-propanol, CH3CHOHCH3(aq). Rubbing alcohol is available in concentrations of 70.% and 91% 2-propanol by volume. To make 100. mL of 70.% aqueous 2-propanol, 70. mL of 2-propanol is diluted with enough water to produce a total volume of 100. mL. In a laboratory investigation, a student is given a 132-mL sample of 91% aqueous 2-propanol to separate using the process of...

The minimum possible average total cost of producing rubbing alcohol in the long run is $2 per bottle. Suppose in the perfectly competitive rubbing alcohol industry firms are receiving a price of $4 per bottle for their product in the short run and there are constant returns to scale. Other things being equal, it follows that:
