Best Answer

The number in front of a molecule tells you how many molecules there are. It is called the coefficient.

Example:

The overall process (really a series of reactions) of photosynthesis can be written in a balanced equation as

6CO2 + 6H2O to form C6H12O6 + 6O2

In this equation there is only one glucose molecule (C6H12O6), but six of each of the other compounds, carbon dioxide, water, and oxygen.

It's called a coefficient, and it tells you how many of a certain molecule are in the formula. Ex: 2H2O tells you that there are 2 H2O molecules, so there are a total of 4 hydrogen and 2 oxygen atoms.
