How would you relate the pressure of H20to the pressure of Hg?

Question

Also, how does the density of Hg (15.6 g/mL) relate to the pressure of hydrogen if the atmospheric pressure was 746 torr?

thank you so much in advance!

Answer 1

Hydrogen? How did that get in? It is a tiny fraction of the atmosphere.
The pressure of a column of water and of Hg is in proportion to their density - 15.6 inches of H20 for every inch of Hg (or of cm or mm)
