Everything else (temperature, atmospheric pressure, environment) being the same, the only factor you need to consider is the (relative) densities of H2O and Hg.
The density of water = 1 g.cm-3 at T=20oC and 1 standard atm.
The density of Hg = 13.5 g.cm-3.
Hence, the pressure for a column of H2O 40 cm high in vacuum is the same as that for a column made of 40 [cm] / 13.5 = 2.96 cm of liquid Hg in vacuum.
* Note that the atmospheric pressure is indicated by the height of the liquid in an inverted tube (open-end facing down) with a (partial) vacuum at the top of the tube.

How many mm Hg is 15 cm H20?
To convert from cm H2O to mm Hg, you can use the conversion factor 1 cm H2O = 0.7356 mm Hg. Therefore, 15 cm H2O is equivalent to 15 cm H2O * 0.7356 mm Hg/cm H2O ≈ 11.03 mm Hg.
What the formula of mercury?
Liquid mercury is a pure element its formula is Hg.
Is Hg a symbol for helium?
The symbol for helium is He. The symbol for mercury is Hg.
What is the formula of Mercury hydroxide?
Mercury (I) Hydroxide Hg OH2 (2 is subscript) Mercury(II) Hydroxide Hg (OH)2
If the atmospheric pressure is 24.9 inches what is the pressure in mm Hg?
To convert inches of mercury (in Hg) to millimeters of mercury (mm Hg), you multiply by 25.4. So, 24.9 in Hg * 25.4 mm/in = 632.46 mm Hg.
What are examples of a liquid?
water(H2O), mercury(Hg).
How to convert mm H2O IN mm hg in?
To convert millimeters of water (mm H2O) to millimeters of mercury (mm Hg), you can use the conversion factor of 1 mm H2O = 0.73556 mm Hg. Simply multiply the value in mm H2O by 0.73556 to obtain the equivalent value in mm Hg.
How many mm Hg is 15 cm H20?
To convert from cm H2O to mm Hg, you can use the conversion factor 1 cm H2O = 0.7356 mm Hg. Therefore, 15 cm H2O is equivalent to 15 cm H2O * 0.7356 mm Hg/cm H2O ≈ 11.03 mm Hg.

Liquid mercury is a pure element its formula is Hg.
How many pascals are equivalent to 1 millimeter of mercury (mm Hg)?
1 millimeter of mercury (mm Hg) is equivalent to 133.322 pascals.
Which has greater surface tension of CH4 H2O H2S and Hg?
Among the given substances, Hg (mercury) has the greatest surface tension due to its strong intermolecular forces and cohesive properties. Mercury's atoms are closely packed, which leads to high surface tension compared to methane (CH4), water (H2O), and hydrogen sulfide (H2S).
How many microns in 1 inch Hg?
There are 25,400 microns in 1 inch of mercury (Hg).
Which term represents the formula Hg?
Hg is the chemical symbol of mercury.
What is the name Hg?
Mercury
Is Hg a molecular element?
No Hg, or mercury is an element, but it is not molecular.
