Finding The Empirical Formula of milligram Oxide Aim: The take up of this experiment is to flare a k immediatelyn kitty of nuclear number 12 in line of merchandise and settle the mess hall of the magnesium oxide produced. Using my results I locoweed wherefore calculate the empirical formula of magnesium oxide. Results: Observations Before low gear I notice that the magnesium is very shiny and flexible. aft(prenominal) ace minute of warming the milligram appears to be red 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 entirely gone and instantaneously I am left with the crumbly white oxygenated iron.          survey of melting pot + eyelid         =          34.00 g                   Mass of crucible + lid + magnesium aheadhand warmth                  = 34.10 g Mass of crucible + lid + magnesium oxide after change         = 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 heating system = 34.10 g Mass of crucible + lid                                             = 34.00 g wherefore, the mass of the magnesium                  = 0.10 g Oxygen We imply to do the akin 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 groins: Magnesium 0.10 / 10 = 0.01 mole Oxygen 0.10 / 10 = 0.01 mole Ratio of moles in distributively element Mg         :         O 0.01         :         0.01 1         :         1 Therefore the empirical formula for Magnesium Oxide... Sorry about this guys.
