The balanced chemical equation for the reaction between H2 and N2 is shown below: Onginally 3.204 g of N2 gas is combined with some H2 in a 2.5 L flask at 150.0 degree C. The mole fraction of N2 in the original mixture (before reaction) is 0.289. Find the partial pressure of the H2 and the partial pressure of the NH3 in the flask AFTER THE REACTION IS COMPLETE, (assuming 100% yield). A 0.675 mol sample of an unknown gas in a noncompressible tank exerts a pressure of 3.95 times 103 kpa (kilopaschals) at 23 degree C. After 60.32 grams of the gas is removed from the tank and the tank is heated, the pressure inside the tank at 45 degree C is 1.01 times 103 kPa. Find the molar mass of the unknown gas.
