## Question:

Reference the following balanced equation: N2O5 (g) + 8H2 (g) → 2NH3 (g) + 5H2O (g)

To form 4.5 grams of H2O, how many grams of N2O5 are needed?

## Mole Ratios:

Mole ratios are used in stoichiometric calculations to help calculate amounts of chemicals consumed or produced. When forming a mole ratio, the numerator is taken to be the coefficient of the chemical you are calculating the amount of. The denominator of the mole ratio is taken to be the coefficient of the chemical the ratio is being multiplied by.
