The conversion factor that would be used to calculate the number of moles of Cl2 produced if 11 moles of HCl were present in the reaction is as follows:
4 mol HCl; 2 mol Cl2
<h3>How to calculate number of moles stoichiometrically?</h3>
The number of moles of a reactant or product of a reaction can be calculated using stoichiometry.
According to this question, the following balanced chemical reaction was given:
4HCl + O2 --> 2Cl2 + 2H2O
This reaction shows that 4 moles of HCl is required to produce 2 moles of Cl2, therefore, this is the conversion factor that would be used to calculate the number of moles of Cl2 if 11 moles of HCl was present.
