C2H5OH + 302 →2C02 + 3H20, what is the mole ratio
of ethanol to water?

The mole ratio  of ethanol to water : 1 : 3

Given

Reaction

C2H5OH + 302 →2C02 + 3H20

Required

The mole ratio

Solution

In a chemical reaction equation, the mole ratio of the reacting compound (reactants or products) is indicated by the reaction coefficient

The reaction coefficient is determined from the number of elements reacting by holding the principle that the number of elements in the reactants is equal to the number of elements in the product

In the above reaction, the ethanol-C2H5OH coefficient is 1 while the reaction coefficient of water-H20 is 3 so that the mole ratio = 1: 3
