Answer:
4.97%.
Step-by-step explanation:
We have been given that a student estimated a mass to be 325 g but upon carefully measuring it found the actual mass to be 342 g. We are asked to find the percent error.
We will use percent error formula to solve our given problem.
[tex]\text{Percent error}=\frac{|\text{Estimate-Actual}|}{\text{Actual}}\cdot 100[/tex]
[tex]\text{Percent error}=\frac{|325-342|}{342}\cdot 100[/tex]
[tex]\text{Percent error}=\frac{17}{342}\cdot 100[/tex]
[tex]\text{Percent error}=0.0497076\cdot 100[/tex]
[tex]\text{Percent error}=4.97076[/tex]
[tex]\text{Percent error}\approx 4.97[/tex]
Therefore, the percent error is approximately 4.97%.
