# 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**.
