Mercury is 13.6 times as dense as liquid water. what would be the reading of a water-filled barometer at normal atmospheric pressure, 760. mmhg?

Density = mass / volume
Because the dimensions of the barometer are the same for each case, we can compare the heights of the liquids instead of the volume.

ρ(mercury) = 13.6ρ(water)
mass(mercury)/760 = 13.6 x mass(water)/Height(water)

Masses of the liquids will also be the same.

Height of water = 13.6 x 760
Height of water = 10,336 mm

The density would be 1.622

Deposition is the transition of matter going from gas to solid without passing through the liquid phase.a.) gas—-> solid
