← An element X forms a volatile chloride that contains 83.5% chlorine by mass. At the same temperature and pressure, the vapour of this chloride is 85.0 times as dense as hydrogen gas. The atomic mass of chlorine is 35.5 u. A student first takes the formula to be XCl. What is the atomic mass of X?In a closed vessel, every reaction below goes to completion. All gas volumes are measured at the same temperature and pressure, high enough for water to stay a vapour. Statement I: 30 mL of hydrogen and 20 mL of oxygen react to give 30 mL of water vapour, and 5 mL of oxygen is left. Statement II: 1.0 L of oxygen, O₂, and 1.0 L of ozone, O₃, contain the same number of oxygen atoms. →
