Consider the following properties of the atmosphere of the planet mars at a particular measurement point on the surface, as measured by the mars rover: average surface pressure: 6.1 mbar average temperature: 210 k atmospheric gas composition (by volume): carbon dioxide (co2) 95.32%; nitrogen (n2) 2.7%; argon (ar) 1.6%; oxygen (o2) 0.13%; carbon monoxide (co) 0.08%.
a. what is the partial pressure of co2 in the martian atmosphere, pa, in units of pa?
b. what is the molar concentration of co2 in the martian atmosphere, ca?
c. what is the total molar concentration of all gases in the martian atmosphere?
d. what is the total mass concentration of all gases the martian atmosphere?

Determine the number of moles of air present in 1.35 l at 750 torr and 17.0°c. which equation should you use? n=pv/rt what is the number of moles present? ⇒ 0.056 mol a sample of n2 gas occupying 800.0 ml at 20.0°c is chilled on ice to 0.00°c. if the pressure also drops from 1.50 atm to 1.20 atm, what is the final volume of the gas? which equation should you use? v2= p1v1t2/p2t1 what is the final volume of the gas? ⇒ 932 ml these are the answers
