The mole ratio in the equation here is 2:1: 2
Explain mole ratio
The ratio of any two substances' amounts in moles during a chemical reaction is expressed as a mole ratio. It comes from the reaction's balanced chemical equation's coefficients. The molar relationship between the reactants and products is represented by the coefficients in a balanced equation.
Mole ratios are essential to stoichiometry because they enable chemists to determine, from the known quantities of other substances involved in a chemical reaction, the amounts of reactants consumed and products formed.
