Gases produced by a chemical reaction can easily be collected over water. To determine the pressure of the dry gas, the vapor pressure of the water at that temperature must be subtracted from the total pressure. 1) Consider the following reaction: Mg(s) + 2 HCI(aq) → MgCl2 (aq) + H2 (g) The total pressure of gas collected over water is 725.0 mmHg and the temperature is 25.0°C What is the pressure of hydrogen gas formed in mmHg? Pressure = mmHg

An empty flask weighs 130.084 g. After vaporization of a sample of volatile liquid at a temperature of 100.0 °C, the flask was sealed, cooled to room temperature, and found to have a mass of 130.316 g. The atmospheric pressure was 759.7 mm Hg. The flask was rinsed and completely filled with water at 18.0 °C. The mass of the water-filled flask was determined to be 379.551 g. What is the pressure of the gas that fills the flask in atmospheres? (Enter your answer as a number without units.)
