Manometers can use liquids other than mercury to measure small pressure differences. On a day when the barometric pressure is 764.3 torr, a water manometer, connected between the atmosphere and a glass bulb containing a sample of helium gas has a height difference of 30.1 cm, The water level is higher in the arm connected to the bulb. Calculate the pressure in the bulb (in torr).
What is this pressure in atmospheres
