Problem: Suppose Daniel has a 3.00 L bottle that contains mixture of O2, N2 and CO2 under a total pressure of 5.50 atm. He knows that the mixture contains .210 mol of N2 and that the partial pressure of co2 is .350 atm. If the temperature is 273 K what is the partial pressure of o2? Please provide the complete solution of this problem.
