## What is the ratio of O2 to CO2?

In every sample of carbon dioxide, there are 32.0g of oxygen present for every 12.0g of carbon. By dividing 32.0 by 12.0, this simplifies to a mass ratio of oxygen to carbon of **2.66 to 1**.

## What is the mole ratio between CO and CO2?

the mole ratio of CO to CO_{2} is 2CO/2CO_{2} or **1/1 or 1**. We’ll get 1 mole of CO_{2} for every 1 mole of CO.

## How do you find the mole ratio?

Find the ratio or the moles of **each element by dividing the number of moles of each by the smallest number of moles**. There are fewer moles of oxygen than any other element, so we will assume one mole of oxygen to establish the ratios.

## What is the ratio of CO2?

The chemical formula tells us the mole ratio. **CO2 = 1 CO2 molecule : 1 C atom : 2 O atoms**.

## Why is mole ratio important?

Mole ratios are important **because mole ratios allow you change moles of a substance to moles of another substance**. … The mole ratios come from the chemical formula or equation.
