A prevailing pressure of one standard atmosphere will support a column of mercury 760 mm in height. Liquid n-propyl iodide has a density of 1.75g/mL. The height of a column of n-propyl iodide that one standard atmosphere can support is________ mm.

The density of liquid mercury is 13.6 g/mL.

Homework Answers

Answer #1

form the barometric calculations

   P = dgh

P = pressure

d = density

h = height

now, density of mercury(d1) = 13.6 g/ml

          g = gravity = 9.8 m/s^2

        h = height of mercury = 760 mm

      density of n-propyl iodide(d2) = 1.75 g/ml

g = gravity = 9.8 m/s^2
        h = height of n-propyl iodide(h2) = ?

   d1h1 = d2h2

13.6*760 = 1.75*h2

h2 = 5906.3 mm

      = 590.6 cm
