Problem 7. (Manometer and Barometer) We are trying to measure the absolute pressure of a gas. The density of mercury is 13.6 g/cm*- A. We first use a manometer to measure the gauge pressure of the gas. The tube to the right is open to the atmosphere, and the liquid in the tube is mercury. What 060 m is the gauge pressure of the gas (assuming the Gas atmosphere is at a pressure of 1 atm). Give your answer in kPa. B. The weather is a little wacky, so we are not confident that the atmospheric pressure is exactly 1 atm. We use a barometer to measure the absolute pressure of the atmosphere - sure enough, it well off from 1 atm. We measure that the height of mercury in the barometer is .81 m. What is the atmospheric pressure Tube in kPa? Mercury C. Given the actual atmospheric pressure determined in part (B), what is the actual absolute pressure in the gas in part (A)? Give your answer in kPa
