If a cetain pressure supports a 256 mm high column of mercury, how high a column of water will it support? The ensity of mercury is 13.6 g/mL. Not completely sure how to work this one, we never reviewed it in class. All the answers to chose from are in inches or ft. I'm coming up with 11.4 ft. Can you show me how to work it?!!
