Part A On a rainy day, a barometer reads 727 mmHg. Convert this value to bars. Express your answer numerically in bars. View Available Hint(s) Learning Goal: 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 kilopascals (kPa), the torr Torr), the bar millibar (mbar). Barometer pressures are sometimes read in millimetres of mercury (mmHg), a unit which is numerically equivalent to the torr. You can convert between units of pressure using conversion factors such as those indicated below. 1 bar = 100 000 Pa = 750 Torr = 750 mmHg (bar), IVO AEO ? bar Submit Previous Answers X Incorrect; Try Again; 3 attempts remaining Figure What is the pressure (in bars) of the gas inside the container connected to an open-end, mercury-filled manometer as shown in the picture? (Figure 1) The atmospheric pressure is 0.95 bar. Express your answer numerically in bars. View Available Hint(s) EVO A ? Gas 18 cm gas pressure = bar Submit
