To calculate the percent error you would use the error in measurement divided by accepted value times 100 correct?

So for an experiment in which you had to find the concentration of a dye in a powdered drink solution, to find the percent error would you use the number you calulated over the real number of the dye and times it by 100?

Experimental value - actual value = D=difference.

%error = (D/actual value)*100

Yes, you are correct. To calculate percent error, you would use the formula:

Percent Error = (Error in Measurement / Accepted Value) * 100

In the case of finding the concentration of a dye in a powdered drink solution, you would first need to determine the error in your measurement, which is the difference between your calculated value and the accepted or known value of the dye concentration.

Let's say you calculated the concentration of the dye to be 4 grams per liter, but the known or accepted concentration is 3 grams per liter. The error in measurement would then be:

Error in Measurement = Calculated Value - Accepted Value
= 4 g/L - 3 g/L
= 1 g/L

Now, to find the percent error, you would use the formula:

Percent Error = (Error in Measurement / Accepted Value) * 100
= (1 g/L / 3 g/L) * 100
≈ 33.33%

Therefore, the percent error in this case would be approximately 33.33%.
