Question

an experiment to determine the volume of a \mole\ of gas was assigned to barry. he didnt the experiment correctly and concluded the volume was 18.7 liters. the actual volume is 22.4 liters. what is the percent error?

Explanation:

Step1: Calculate the error

The error is the absolute difference between the actual value and the experimental value. So, \(|22.4 - 18.7|=3.7\)

Step2: Calculate the percent error

The formula for percent error is \(\frac{\text{Error}}{\text{Actual Value}}\times100\%\). Substitute the values: \(\frac{3.7}{22.4}\times 100\% \approx 16.5\%\)

Answer:

16.5%
