A liquid is used to make a mercury-type barometer. The barometer is intended for space-faring astronauts. At the surface of the Earth, the column of liquid rises to a height of 2185 mm, but on the surface of Planet X, where the acceleration due to gravity is ¼ its value on Earth, the column only rises to a level of 725 mm. Find the density of the liquid and the atmospheric pressure at the surface of Planet X
