One Mole of Silver Nitrate contains 1 Mole of Silver, 1 Mole of Nitrogen and 3 Moles of Oxygen. Note that 1 Mole of Oxygen is 15.9994 grams, which is about 13.5 cubic feet.

From the table above, we can see that 1 Mole of Silver Nitrate weighs about 169.87 grams. You can then say that the Formula Weight of Silver Nitrate is 169.87 grams. The terms Formula Weight and Molecular Weight mean the same thing.

What is a Mole?

A Mole is the standard unit of measure in Chemistry, in the way that a Gallon is to Gasoline. One Mole is 6.02 times 10²³ atoms or molecules, meaning groups of atoms.

An Interesting Fact

Silver Nitrate has a Density of 4.35 grams per cubic centimeter when compressed, and 2.21 grams per cubic centimeter in powder form. So if 1 Mole of Silver Nitrate weighs 169.87 grams, 1 Mole of Silver Nitrate has a volume of 169.87 divided by 4.35, or 39.05 cubic centimeters.

Even More Interesting

Silver Nitrate contains 4 Moles of gasses, being 1 Mole of Nitrogen plus 3 Moles of Oxygen. Four Moles of gasses normally occupy 13.5 cubic feet per Mole.

• 13.5 cubic feet times 4 equals 54 cubic feet.
• 54 cubic feet converts to 1,529,109 cubic centimeters, or 404 gallons.
• So the gasses in 1 Mole of Silver Nitrate have shrunk from 1,529,109 cubic centimeters down to 39.05 cubic centimeters, a factor of 39,157 times.
• In plain terms, 404 gallons of gasses shrunk to 0.0103159 gallons, which is about 8 teaspoons.
