Respuesta :
The mass of sodium chloride is less then 76g.
Explanation: NaOH is limiting reagent (1 mol), HCl is excessive reagent (>1 mol). NaCl will be 1 mol (equal to NaOH) in the reaction: HCl + NaOH -> NaCl + H2O.
Mass of NaCl will be: 1 mol * 58.5 g/mol = 58.5 g < 76 g.
The answer is The mass of sodium chloride formed is less than 76 grams.
Remember Mass is never gained or loss in any chemical reactions
So,
hydrochloric acid + sodium hydroxide => sodium chloride + water
Total 76 gram Total will also 76 gram
In this case, the mass of sodium chloride will be less than 76 gram because we need to take out the mass of the water.
