They come from the coefficients in the balanced equation.

For example, in the equation:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

The molar ratios are CO₂:H₂O:C₆H₁₂O₆:O₂ = 6:6:1:6.

We can break this down for any two pairs of compounds.

The molar ratio of CO₂:C₆H₁₂O₆ = 6:1.

The molar ratio of CO₂:O₂ = 6:6

The molar ratio of C₆H₁₂O₆:O₂ = 1:6, etc.
