13) A 2.30 g sample of white solid was vaporized in a 345 mL vessel. If the vapor has a pressure of 985 mm Hg at 148 °C, what is the molar mass of the solid? 14) Magnesium metal reacts with hydrochloric acid to produce hydrogen gas, H₂. Mg (s) + 2 HCl (aq) MgCl, (aq) + H₂(g) Calculate the volume in liters of hydrogen produced at 33 °C and 665 mm Hg from 0.0840 moles of Mg and excess HCI. M 15) A 200.0 mL flask contains 1.03 mg O₂ and 0.56 mg He at 15 °C. Calculate the partial pressures of oxygen and of helium in the flask. What is the total pressure?
