Consider a chemical reaction in which hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH) to produce sodium chloride (NaCl) and water (H2O). This reaction is a classic example of a neutralization reaction in stoichiometry. If scientists have already determined that the reaction is balanced and proceeds to completion under standard conditions, using your understanding of stoichiometry, the law of conservation of mass and the fundamental principles of Chemistry, how would you determine the amount of sodium chloride that can be produced from a known quantity of hydrochloric acid and sodium hydroxide, given the precise molar mass of all compounds involved?

The amount of sodium chloride that can be produced from a known quantity of hydrochloric acid and sodium hydroxide can be determined by simply adding the masses of the reactants.

The amount of sodium chloride that can be produced from a known quantity of hydrochloric acid and sodium hydroxide can be determined by using the stoichiometry of the reaction and the amount of moles of the limiting reactant.

The amount of sodium chloride that can be produced from a known quantity of hydrochloric acid and sodium hydroxide can be determined by subtracting the mass of water produced from the total mass of reactants.

The amount of sodium chloride that can be produced from a known quantity of hydrochloric acid and sodium hydroxide can be determined by dividing the mass of the reactants by the molar mass of sodium chloride.

The amount of sodium chloride that can be produced from a known quantity of hydrochloric acid and sodium hydroxide can be determined by multiplying the mass of the reactants by the molar mass of sodium chloride.
