sineoko [7]

Answer:

86% is the percent yield of the reaction

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 =

<h3>86% is the percent yield of the reaction</h3>

zaharov [31]
If he was 30.8% too low, it means that he was at 69.2% of the boiling point needed. So 50o C is 69.2% of total.

In order to know what 100% is, you can divide the number by it's percentage and then multiply it by a hundred.

So: 50/30.8=1.623
1.623*100=162.3
So the correct boiling point of the liquid he was working with in the lab is 162.3 oC
