Use the balance chemical equation to determine the theoretical yield of the salt

Question

Use the balance chemical equation to determine the theoretical yield of the salt produced. To do this you need to determine the moled of acid or base (pick one) used in the mixture you heated based on the molarity of the solution and the volume og the acid or base used (M=moles/L). Use your balanced chemical equation, the reation's stochiometric ratios, and the moles you just determined to calculate the moles of salt produced. Finally convert the moles to grams.

HCl(aq) + NaOH(aq)-> NaCl(aq) + H20(l)

We used 35mL of 0.5M NaOH and 35mL of 0.5M HCl and put it in a beaker to heat.

Before rxn: beaker + watch glass=132.5428g

After rxn: beaker + watch glass = 133.5209g

Salt=0.9781g

Can someone please explain the steps, I would appreciate it.

Explanation / Answer

1 mole of acid reacts with 1 mole of base to form 1 mole of salt

moles of acid = moles of base = molarity x volume = 0.5 M x 0.035 L = 0.0175 mols

So theoretical yield of salt produced = 0.0175 mol x 58.44 g/mol = 1.0227 g

Percent yield of reaction = (0.9781/1.0227) x 100 = 95.64%
