A closed container is filled with oxygen. the pressure in the container is 405 kpa . what is the pressure in millimeters of mercury? express the pressure numerically in millimeters of mercury.

Respuesta :

1 mm Hg pressure is the pressure due to 1 mm height of mercury

so it is given as

[tex]P = \rho g h[/tex]

[tex]P = 1 * 10^{-3} * 13700 * 9.8 = 134.26 Pa[/tex]

now we know that pressure is

P = 405 kPa

[tex]P = 405 * 10^3 Pa[/tex]

so in mm Hg this pressure is

[tex]P = \frac{405 * 10^3 }{134.26} = 3016.5 mm Hg[/tex]

so pressure in millimeter Hg will be 3016.5 mm Hg
