Instead, it is extracted by electrolysis. The ore is first converted into pure aluminium oxide by the Bayer Process, and this is then electrolysed in solution in molten cryolite - another aluminium compound. The aluminium oxide has too high a melting point to electrolyse on its own. The usual aluminium ore is bauxite.

Given
40 °C measurement
Required
The percent error
Solution
% Error : difference between the theoretical value and the actual value
or
% Error : Absolute Error / Accepted Value
Absolute Error = Measured Value - Accepted Value
% Error for Chemistry student :
1. Subtract the measurement value with the accepted value
= 40 °C - 43.2 °C
= -3.2 °C
2. Divide by the accepted value, and multiply by 100
= |-3.2/43.2| x 100%
= 7.4%
Answer:
Moles = Molecules / (6.0221415 x 10^23)
