Question

The organic compound di-n-butyl phthalate, C16H22O4(l), is sometimes used as a low-density (1.046 g·mL–1) manometer fluid. Compute the pressure (in torr) of a gas that supports a 463-mm column of di-n-butyl phthalate. The density of mercury is 13.53 g·mL–1.

The organic compound di-n-butyl phthalate, C16H2204(), is sometimes used as a low-density (1.046 g mL) manometer fluid. Compute the pressure (in torr) of a gas that supports a 463-mm column of di-n-butyl phthalate. The density of mercury is 13.53 g mL-1 Number Torr

Explanation / Answer

Pressure of the gas can be calculated as

P = (Density of fluid/density of Hg)*length of column

P = (1.046g/mL/13.53g/mL)*463 mm = 35.79 torr
