Aqueous hydrobromic acid reacts with solid sodium hydroxide to produce aqueous sodium bromide and liquid water . if 12.6 g of water is produced from the reaction of 72.8 g of hydrobromic acid and 71.3 g of sodium hydroxide, calculate the percent yield of water. round your answer to 3 significant figures.
Accepted Answer
Here's how to calculate the percent yield of water in this reaction:
1. Balanced Chemical Equation:
HBr(aq) + NaOH(aq) → NaBr(aq) + H₂O(l)
2. Calculate Theoretical Yield:
- Convert the masses of HBr and NaOH to moles using their molar masses.
- Determine the limiting reactant. The reactant that produces the least amount of water is the limiting reactant.
- Calculate the theoretical yield of water (in grams) using the mole ratio from the balanced equation and the moles of the limiting reactant.
3. Percent Yield:
- Divide the actual yield (12.6 g) by the theoretical yield and multiply by 100%.
