Moles and Titrations

The mole is simply the name given to a certain number

A mole is this many: 602 300 000 000 000 000 000 000

1) That's all it is- just a number. So, why this number?

2) The answer is that when you get precisely that number of atoms of carbon-12 it weighs exactly 12g. So get that number of atoms or molecules of any element or compund and conveniently, they weigh exactly the same number of grams as the relative atomic mass of the element or compound.

3) So, you can use moles as a unit of measurment when you're talking about a substance.

Concentration is a measure of how crowded things are

The concentration of a solution can be measured in moles per dm³
