Homework Answers
Hii
Metal to oxygen ratio should come same for your and other batch.
Then we can infer that there is a constant proportion between the metal and the oxygen for formation of the oxide.
I have shown a sample calculation below.
This experiment is not accurate there may be little error while measuring by either of your batch.
Please do the experiment again and if you need help comment in the comment window.
I am showing a sample calculation in the pic below .
Hope
this helps
Thank you
