## 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 a mole chemistry question?

The mole concept

A mole is defined as the amount of substance that contains as many elementary particles (atoms, molecules or ions) as there are atoms in 12 g of carbon-12 isotope. • The number of atoms or ions in 1 mole of an element or compound is 6.02 x 10^23 and is called Avogadro’s number (NA). •

## What is a mole in chemistry quizlet?

The mole is the amount of substance that contains as many particles (molecules, ions or atoms) as there are in 12g of carbon. This number has been found to be 6.02 x 10^23. Molar Mass (M) Numerically equal to the relative molecular mass of each element in a molecule.

## What is the mole ratio of CO2 to H2O?

The chemical formula tells us the mole ratio. CO2 = 1 CO2 molecule : 1 C atom : 2 O atoms. 1 C12H22O11 molecule: 12 O2 molecules : 12 CO2 molecules : 11 H2O molecules.

## What is the theoretical mole ratio?

The mole ratio is the stoichiometric ratio between the amount of one compound and the amount of another compound in a reaction. For this reaction, for every two moles of hydrogen gas used, two moles of water are produced. The mole ratio between H2 and H2O is 1 mol H2/1 mol H2O.
