A sample of gas has an initial volume of 2.8 L at a pressure of 753 mmHg .If the volume of the gas is increased to 3.6 L, what will the pressure be? (Assume constant temperature.) Express your answer using two significant figures.
You are given an open-ended mercury manometer and asked to determine the pressure in a pipleline that supplies feed gas to a reactor. However, when you connect the manometer to the pipeline, you noticed that the calibration markings in the leg tha..
