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 515 mm column of di‑n‑butyl phthalate. the density of mercury is 13.53 g⋅ml−1

Pressure will be 68285.91 kPa or 512186.45 Torr

Explanation:

The pressure in a manometer is calculated using following formula

Pressure = height X density X acceleration due to gravity

Given:

Height= 515 mm =0.515 m

density = 13.53 g/mL = 13530 kg / m³

we know

acceleration due to gravity = 9.8 m / s²

Putting the values

pressure = 0.515 X 13530 X 9.8 = 68285.91 kPa

1 kpa = 7.5 torr

68285.91 kPa = 512186.45 Torr

passing a magnet thought the

mixture , because iron gets attracted to magnet .
