Percent error in chemistry help!

[From: ] [author: ] [Date: 12-06-16] [Hit: ]
There is no error. You have 0% error.......
So I've already calculated that the specific heat of zinc is 0.39
Now, I have this question and I have no idea how to solve it

Use the given specific heat capacity values below to calculate the percent error of the experimental specific heat capacity that you determined in Part I of the lab.

Known specific heat values — Iron: 0.444 J/g°C; Zinc: 0.390 J/g°C; Copper: 0.385 J/g°C, Aluminum: 0.900 J/g°C

| experimental - actual value | x 100 %
actual value

-
experimental value = 0.39
actual value (known) = 0.39

Now you plug in.

9(.39-.39)x100%)/.39 = 0%

So, you have 0% error. That would make sense, given that your experimental results was THE SAME as the known value. It's the same. There's no difference. There is no error. You have 0% error.
