Answer
The percent yield for the reaction is 106.77%
Explanation
Given:
Moles of Na = 2.42 mol
Actual yield of table salt (NaCl) produced = 151 g
What to find:
The percent yield for the reaction.
Step-by-step solution:
The first step is to write a balanced equation for the reaction.
2Na + Cl₂ → 2NaCl
From the equation,
2 moles of Na produced 2 moles of NaCl
So, 2.42 moles of Na will produce x moles of NaCl
The value of x is calculated below
[tex]x=\frac{2.42\text{ }mol\text{ }Na}{2\text{ }mol\text{ }Na}\times2\text{ }mol\text{ }NaCl=2.42\text{ }mol\text{ }NaCl[/tex]The next step is to calculate the theoretical yield of NaCl.
1 mole NaCl = 58.44 grams
2.42 moles NaCl = x grams
[tex]x=\frac{2.42mol}{1mol}\times58.44\text{ }grams=141.4248\text{ }g\text{ }NaCl[/tex]The final step is to calculate the percent yield using the formula below:
[tex]Perecent\text{ }yield=\frac{Actual\text{ }yield}{Theoretical\text{ }yield}\times100\%[/tex]Actual yield = 151 g
Theoretical yield = 141.4248 g
Thus,
[tex]Percent\text{ }yield=\frac{151g}{141.4248g}\times100\%=106.77\%[/tex]The percent yield for the reaction is 106.77%
