Answer:
86% is the percent yield of the reaction
Step-by-step explanation:
Percent yield is defined as 100 times the ratio of actual yield / theoretical yield.
Based on the reaction:
2Na + Cl₂ → 2NaCl
The theoretical yield is 0.50 moles because 0.50 mol of Na are added in the beginning. As 0.43 moles are produced, actual yield is 0.43 mol. And percent yield is:
0.43mol / 0.50mol * 100 =
86% is the percent yield of the reaction
