stoichiometry

stoichiometry can be simplified as grams to moles to moles to moles to grams.
we worked on that this week.
we also did a lab called oxidation of magnesium.
in that lab, we burned magnesium ribbon.
before, we weighed the cruicible.
after, we weighed the magnesium oxide with the cruicible.
we had 31.67% error on ours, because we didn't scrape out the scraps from the previous period.
now, i am going to get my blog posts checked.
