A mixture of Nitrogen and Argon gases in a balloon exerted a pressure of 2.55 atm. Given that there were 1.0 g nitrogen gas and 3.2 g argon gas in the balloon, calculate the partial pressure of argon gas.
Calculate moles Ar and moles N2, find total moles, and calculate mole fraction of each.
Then XAr x total P = partial pressure Ar
