A closed container is filled with oxygen. The pressure in the container is 345 kPa. What is the pressure in millimeters of mercury?
Express the pressure numerically in millimeters of mercury.
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 = 760 mmHg = 101, 325 Pa
