What is the formula used to calculate the number of moles in a given sample?

Answer: To calculate the number of moles present in a solution, take the molarity of the solution and multiply it with the volume of the solution (in liters). This gives the number of moles present in the solution.

How do you find the complete reaction in chemistry?

A reaction is "completed" when it has reached equilibrium — that is, when concentrations of the reactants and products are no longer changing. If the equilibrium constant is quite large, then the answer reduces to a simpler form: the reaction is completed when the concentration of a reactant falls to zero.
