2c4h10 + 13o2 8co2 + 10h2o what is the mole ratio of butane to carbon dioxide?

The mole ratio of butane to carbon dioxide is 1 : 4

Explanation:

Mole ratio is defined as the ratio of number of moles of the two substances taken into account.

In a chemical reaction, the stoichiometric coefficients represents the number of moles.

For a given chemical equation:

By stoichiometry of the reaction:

2 moles of butane reacts with 13 moles of oxygen to produce 8 moles of carbon dioxide and 10 moles of water.

So, the mole ratio of butane to carbon dioxide in a given chemical reaction is 2 : 8 or 1 : 4
