Question

Im not sure how to calculate the absolute percent error?

. Calculate the average molar volume. 24.45% mot 23 lunches =47.45 = 23.725 Ymo . Calculate the absolute % error for the average molar volume.

Answer 1

Absolute percentage of error =((avergae value- observed value)/ Average Value )* 100%

for 24.45 L the percentage of error can be calculated in the following way:

Average Molar volume = 23.725, round off to 23.73 L/ mol that is also known as accepted value

Error for data 1, molar volume 24.45 L/ mol = ((23.73- 24.45)/24.45)* 100%= -2.9%, the negative sign can be ignored and the % of error= 2.9

Error for data 2, 23.00 L/ mol = ((23.73- 23.00)/24.45)* 100%= 2.9%

In this way for any number of data the % of error can be calculated easily

Thanks
