Question

We mix 193 grams of oxygen gas with
39 grams of argon gas in a volume of 1140 mL
at 37C. What will be the final pressure of the gas mixture?

Answer 1

Use PV = nRT and solve for pO2 gas by itself. n = 193/32 = ?

Then PV = nRT and solve for pAr gas by itself. n = 39/atomic mass Ar.

Then ptotal = pO2 + pAr

Answer 2
