Aqueous hydrochloric acid reacts with solid sodium hydroxide to produce aqueous sodium chloride and liquid water . if 2.79 g of sodium chloride is produced from the reaction of 2.2 g of hydrochloric acid and 3.3 g of sodium hydroxide, calculate the percent yield of sodium chloride. round your answer to 2 significant figures. What is the answer?
Accepted Answer
Here's how to calculate the percent yield:
1. Write the balanced chemical equation:
HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l)
2. Determine the limiting reactant:
- Convert the masses of HCl and NaOH to moles using their molar masses (HCl: 36.46 g/mol, NaOH: 40.00 g/mol).
- Calculate the moles of NaCl produced from each reactant using the mole ratio from the balanced equation.
- The reactant that produces the least amount of NaCl is the limiting reactant.
3. Calculate the theoretical yield:
- The theoretical yield is the maximum amount of NaCl that can be produced from the limiting reactant. Calculate this based on the moles of NaCl produced from the limiting reactant.
4. Calculate the percent yield:
- Percent yield = (actual yield / theoretical yield) x 100%
- Substitute the actual yield (2.79 g) and the calculated theoretical yield. Round the answer to 2 significant figures.
