It is possible to make a barometer using a liquid other than mercury. What would be the height (in meters) of a column of dichloromethane at a pressure of 0.400 atm, given that 0.400 atm is equal to a 0.304 m column of mercury and the densities of mercury and dichloromethane are 13.5 g/cm3 and 1.33 g/cm3, respectively.

There's a BIG problem with this problem. (Repetition intended). Methylene chloride is a volatile solvent. (B.P. 39oC) This means the closed end is under a considerable vapor pressure and - - at room temperature 0.4 atm is above its boiling point (400mmHg @ 24oC).
This will not work.

(0.304 m) x (13.5 g/cm^3 / 1.33 g/cm^3) = 3.09 m dichloromethane
So answer B.

Mercury is 10.15 times the density of dichlor, so the diclhor column will be 10.15 times higher.
