What is the percent error You measure the mass of a model car to be 230 G the actual mass is 218 grams what is your percent error?

To calculate the percent error, use the formula: (\text{Percent Error} = \left(\frac{\text{Measured Value} - \text{Actual Value}}{\text{Actual Value}}\right) \times 100). In this case, the percent error is (\left(\frac{230 , \text{g} - 218 , \text{g}}{218 , \text{g}}\right) \times 100 \approx 5.50%). Thus, the percent error in your measurement is approximately 5.50%.
