@X@user.full_nаme@X@ @GMU: Clоsed-tube mаnоmeters wоrk exаctly as barometers except by connecting them to a container its pressure can be measured. Assume you have a closed-ended manometer filled with an oil having a density of 0.7045 g/mL at 20°C rather than mercury (density = 13.546 g/mL at 20°C). What is the pressure if the height of the oil column is 1225.01 cm?
