Sketch each molecular orbital.
Solution :Step 1 : Here we have to calculate pressure of the gas enclosed in torr for the situations given :(a) The mercury in the arm attached to the gas is 15.4 mm higher than in the one opento the atmosphere; atmospheric pressure is 0.985 atm :Given, height of the mercury = 15.4 mm Atmospheric pressure = 0.985 atm. Now let’s convert 0.985 atm to torr : 1 atm = 760 torr Hence, 0.985 atm in torr is : = 748.6 torr. Therefore, 0.985 atm in torr is 0.684 . Now , let’s determine the pressure of the liquid : 1 mmHg = 1 torrThe mercury in the arm of the manometer is 15.4 mm higher than in the one open toatmosphere, indicating pressure inside the container is lower than the atmospheric pressure. Hence, PgasPatm h = 748.6 torr - 15.4 torr = 733.2 torr.Hence, pressure of the gas in the manometer is 733.2 torr.
