On a certain day a laboratory barometer indicates that the atmospheric pressure is 786.2 torr. A sample of gas is placed in a flask attached to an open-end mercury manometer, and a meter stick is used to measure the height of the mercury in the two arms of the U tube. The height of the mercury in the open-end arm is 80.4 mm, and the height in the arm in contact with the gas in the flask is 123.5 mm. What is the pressure of the gas in the flask (a) in atmospheres, (b) in kilopascals?
