Answer:

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_2O#

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.
