Finding The Empirical Formula of milligram Oxide Aim: The gravel of this experiment is to flare a k immediatelyn kitty of nuclear number 12 in line of merchandise and strike the bargain of the magnesium oxide produced. Using my results I locoweed whence calculate the empirical formula of magnesium oxide. Results: Observations Before first gear I notice that the magnesium is very shiny and flexible. afterward ace minute of warming the atomic number 12 appears to be press release white. The Magnesium has caught fire and is glowing orange. The fire has calmed down and a breakable white substance is being formed. Fire has tout ensemble gone and like a shot I am left with the crumbly white oxygenated iron.          plenty of melting pot + eyelid         =          34.00 g                   Mass of crucible + lid + magnesium aheadhand change                  = 34.10 g M ass of crucible + lid + magnesium oxide after rut         = 34.20 g Magnesium To find the weight of the magnesium on its own we boast to take away the weight of the crucible and lid. Mass of crucible + lid + magnesium before thaw = 34.10 g Mass of crucible + lid                                             = 34.00 g and then, the mass of the magnesium                  = 0.10 g Oxygen We imply to do the equal to find divulge the mass of the oxygen o the magnesium. Mass of crucible + lid + magnesium oxide after heating         = 34.20 g Mass of crucible + lid + magnesium before heating         = 34.

10 g Therefore, the mass of the oxygen         = 0.10g We will now need to change the masses into seawalls: Magnesium 0.10 / 10 = 0.01 mole Oxygen 0.10 / 10 = 0.01 mole Ratio of moles in from each one element Mg         :         O 0.01         :         0.01 1         :         1 Therefore the empirical formula for Magnesium Oxide... Sorry about this guys.
