To get my constant I just did 1/42.704 grams which was the 3 gas %'s added up. I may be doing it completely wrong.

That's what I have in my notes.

Awesome, thanks for explaining an easier way too!

Ok redid some work Density = (P * MW) / (R * T) 0.9869231693139999 atm Molecular weight of 2 g/mol R = 0.08206 L*ATM / mol*K T = 283.15K 1.97384/23.235289 = 0.08495 g/L specific volume = 1/density specific volume of hydrogen = 11.77163 g/L Maybe yes?

Ok so I don't know why I typed 2kg of hydrogen. Its a sample of hydrogen which is 1 gram but since Hydrogen is H2 in the atmosphere it should be 2 grams which is 2 moles correct?

Homework Statement Determine the mean molecular weight of the Martian atmosphere which is composed of 95% carbon dioxide, 3% nitrogen, 1.6% argon. What is the gas constant for 1kg of such an atmosphere? Using the value for R from the last problem assuming the surface temperature of Mars is...
