Question

to calculate the percent error (% error) we use: |experimental value - actual value| / actual value x 100 = % error. determine the percent error is a student experimentally obtained a value of 4.8 m but the procedure called for a solution that was 4.5 m. options: 6.7%, 0.067%, 30%, 3%

Explanation:

Step1: Identify values

Experimental Value = 4.8 M, Actual Value = 4.5 M

Step2: Apply percent error formula

Percent Error = $\frac{|Experimental\ Value - Actual\ Value|}{Actual\ Value} \times 100$
Substitute values: $\frac{|4.8 - 4.5|}{4.5} \times 100 = \frac{0.3}{4.5} \times 100$

Step3: Calculate

$\frac{0.3}{4.5} \times 100 \approx 6.7\%$

Answer:

6.7%
