In the planet Mars the average temperature is around `-53^(@)C` and atmospheric pressure is 0.7 kPa. Calculate the number of moles of the molecules inunit volume in the planet Mars.

Text Solution

Verified by Experts

Average temperature of the mass `T= - 53^(@)C`
Atmospheric pressure `P= 0.9 xx 10^(3) P`
Volume V=1 `m^(3)`
Number of moles `n=?`
`mu _(mass) = (V P)/(RT ) = (0.9xx 10^(3))/(8.314 xx 220) = 0.38 `mol
`M_(e ) = 0.38 ` mol
