What is the Experimental Value if there was a -15.6% error in students' experimental value?
Calculation of Experimental Value with Error Percentage
To find out the experimental value when there was a -15.6% error in the students' experimental value, we need to calculate the corrected value by adjusting for the error percentage. The actual value given is 25.7 ml.
Final answer:
The experimental value can be calculated by subtracting the error percentage from the actual value.
Explanation:
The experimental value can be calculated by subtracting the error percentage from the actual value. In this case, if the error was -15.6%, the experimental value can be found by multiplying 15.6% of 25.7 ml by -1 and subtracting it from 25.7 ml.
15.6% of 25.7 ml = 0.156 * 25.7 ml = 4.0042 ml
Experimental value = 25.7 ml - 4.0042 ml = 21.6958 ml
Therefore, the experimental value is approximately 21.7 ml.
What is the formula to calculate the experimental value when there is an error percentage in the measurement? The formula to calculate the experimental value when there is an error percentage is: Experimental value = Actual value - (Error percentage * Actual value)
