Opps! The second question, I divide the number of moles of oxygen atoms by (2X16) instead of just 16. I plotted the graph and I got the answer correct. But the comment on the graph is wrong since my table is wrong, which mean my y-axis also wrong. So my question 2 gone :'(

At first I plotted that...but then I sensed something fishy and changed it back to divide the mass over 16. ..And table with pencil is fine!

What about writing the headings in pencil?
