# What do the reactant and the product tell us about the molar ratio?

Apr 9, 2017

The coefficients in front of the products and reactants give the molar ratio.

#### Explanation:

The coefficients are the numbers in front of each molecule or element.

$2 {H}_{2} + 1 {O}_{2} = 2 {H}_{2} O$

The coefficient for Hydrogen is 2
The coefficient for Oxygen is 1
The coefficient for Water ( Hydrogen Oxide) is 2

The ratio for molar ratio of Hydrogen to water is 2/2

The ratio for molar ratio of Oxygen to water is 1/2

The molar ratio depends on the coefficients in the balanced chemical equation.
