Question

In the reaction 2co (g) + o2 (g) → 2co2 (g), what is the ratio of moles of oxygen used to moles of co2 produced?

Answer 1

Answer:

1 : 2

Explanation:

Let's bring out the balanced chemical equation.

2CO (g) + O2 (g) → 2CO2 (g)

From the equation, we can tell that 1 mole of oxygen reacts to produce 2 moles of Carbon dioxide.

The ration is given as;

Moles of oxygen = 1

Moles of Carbon dioxide = 2

Moles of oxygen : Moles of Carbon dioxide

1 : 2

Answer 2

The ratio of moles of oxygen used to moles of co2 produced is 1 : 2.

What are moles?

In the International System of Units, Mole is the base unit of the amount of any substance.

The balanced chemical equation is

$\rm 2CO (g) + O_2 (g) = 2CO_2 (g)$

In the chemical equation, we can see that 1 mol of oxygen reacts to produce 2 mol of carbon dioxide.

By stoichiometry

1 : 2

Moles of oxygen : Moles of Carbon dioxide

1 : 2

Thus, the ration of mole is 1:2.
