Your starting point here is the balanced chemical equation for this neutralization reaction "KHP"_text((aq]) + "NaOH"_text((aq]) -> "KNaP"_text((aq]) + "H"_2"O"_text((l]) The important thing to notice … WebThe idea would be to turn grams of the reactant into moles of the reactant using the molar mass of the reactant, then multiply by the mole-to-mole ratio in the balanced chemical equation to get moles of your product. And then we could also find the grams of the product if they asked us to by using the molar mass of the product.
