a) A 15.0 L container contains 7.0 g Hz(g) (molar mass = 2.02 g/mol), 44.0 g N2(g) (molar mass = 28.01 g/mol) and 65.6 g of an unknown gas. The temperature is 25.0°C and the total pressure is 13.5 atm. What is the molar mass of the unknown gas and what is its partial pressure in the mixture? b) Assume that A- is a weak base. We mix 2.00 L of a 0.444 M NaA solution with 1.00 L of a 0.222 M HCI solution (total volume is 3,000 L). The base ionization constant of A- is Kb = 5.68 x 10-¹⁰. What is the pH of the solution formed?
