Problem- Assume that you have an open-end manometer filled with ethyl alcohol (density = 0.7893g/mL at 20 ?C) rather than mercury (density = 13.546g/mL at 20 ?C).
What is the pressure (in pascals) if the level in the arm open to the atmosphere is 54.5cm higher than the level in the arm connected to the gas sample and the atmospheric pressure reading is 755.8mm Hg?
Anyone can tell me how to solve it step by step so that I will be able to understand what is going on?
