Hello!</h2>
The answer is:
The third option, 79.8%
<h2>
Why?</h2>
To calculate the percent yield we need to divide the actual yield by the theoretical yield, and then, multiply it by 100 in order to find the percent.
So, we from the statement we know the following information:
Let's use the following formula and substitute the given information:
Hence, we have that the correct option is the third option, the percent yield is 79.8%.
Have a nice day!

Answer:
- Acid-Base reaction (the reactanct acting as a base is NaOH)
Explanation:
The reaction that takes place is:
- C₃H₅O(CO₂H)₃(aq) + 3OH⁻ (aq) → C₃H₅O(CO₂)₃⁻³(aq) + 3H₂O(l)
This is a <em>acid-base reaction</em>, with the citric acid acting as the acid and the <u>sodium hydroxide NaOH acting as the base.</u>
We <u>calculate the moles of citric acid</u> using the information from the titration:
- 0.0142 L * 0.340 M *
= 1.609x10⁻³ mol citric acid
Now we <u>convert moles to mass</u> using the acid's molecular weight (192.13g/mol):
- 1.609x10⁻³ mol citric acid * 192.13g/mol = 0.3092 g citric acid
Finally we calculate the mass percent of citric acid in the sample:
- 0.3092 g / 16.00 g * 100% = 1.93%
