Question

To understand several methods of measuring gas pressure. Gases exert a measurable pressure (p) on the walls of their container. The SI unit for pressure is the pascal (pa). Other pressure units frequently used in chemistry are millimeters of mercury (mmHg) and atmospheres (atm). You can convert between units of pressure using conversion factors such as those indicated below. 1 atm = 700 mmHg = 101,325 Pa On a rainy day, a barometer reads 731 mmHg. Convert this value to atmospheres. Express your answer numerically in atmospheres. A closed container is filled with oxygen. The pressure in the container is 265kPa . What is the pressure in millimeters of mercury? Express the pressure numerically in millimeters of mercury. What is the pressure (in atmospheres) of the gas inside the container connected to an open-end, mercury-filled manometer as shown in the picture? The atmospheric pressure is 0.95 atm. Express your answer numerically in atmospheres.
