Determine the percentage error.

Question

So we found that aluminium has a specific heat capacity of 18441J/KgC

And I know that the percentage error = mv-av/av x 100%

But how do we know the actual value of aluminium? My teacher never gave it to us. And when it says mv-av does it mean the measured values actual value?

Thank you!!

Answer 1

google it: Aluminum 0.900kJ/KgC

you got 18kJ/kgC

Your percent Error is fantastic. Recheck your calculations.
