On a cool, rainy day, the barometric pressure is 746 mmhg. calculate the barometric pressure in centimeters of water (cmh2o) (d of hg = 13.5 g/ml; d of h2o = 1.00 g/ml).

100.71 cm H2O

Explanation:

In a fluid column barometer, the height of the fluid column is proportional to the pressure. The pressure is by definition:

, where F is a force and A is the area.

In a column barometer the force is given by the weight of the fluid:

, and the mass may be expressed as , where is the density and V is the volume.

Replacing this in the pressure definition:

In a constant cross section area column, the volume may be calculated as:

where A is the area and h the height. Replacing this in the previous equation:

Different columns may be over the same pressure, so:

Dividing each part for gravity constant:

And isolating hw:

mm

It is equal to 1007,1 cm.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
