The formula to calculate percent error is:

$\text{Percent Error} = \left( \frac{|\text{Experimental Value} - \text{Accepted Value}|}{\text{Accepted Value}} \right) \times 100$

Here, the accepted value is 947 mL, and the experimental value is 934 mL.

Now, plug in the values:

$\text{Percent Error} = \left( \frac{|934 - 947|}{947} \right) \times 100$ $\text{Percent Error} = \left( \frac{13}{947} \right) \times 100$ $\text{Percent Error} \approx 1.37\%$

So, the student's percent error is approximately 1.37%.
