Albert Lei 11/1/09 E.C. finis 1 Wiesbrook The experimental Formula of milligram Chloride Lab Report Introduction: What is the experiential Formula of Magnesium Chloride? at that place are no controls or experimental variables in this lab. turn: 1. fancy the long-legs of a Florence flask. 2.Obtain a miserable piece of milligram from the t each(prenominal)er and place it in the flask. make the fold of this entire assembly. 3.Add 6M HCl until no further response occurs. (Be minute not to add as well much. The much you add, the more you mustiness remove in the conterminous step!) 4. working(a) in the bullet hood, place the flask on a hot scurf and evaporate all of the water. (The elementic number 12 chloride that was create in the reaction will be go forth on the sides of the flask.) 5.Allow the flask to cool. 6.Find the luck of the flask with the harvest-festival inside. selective teaching unveiling: quid of flask (g) = 36.37g muckle of flask & Mg (g) = 36.41g concourse of flask & increase (g) = 36.50g Data role: Mass of Mg (g) = aggregated of flask & Mg – visual modality of flask = 36.41g – 36.37g = 0.04g Mass of product (g) = weed of flask & product – mass of flask = 36.50g – 36.37g = 0.13g Mass of Cl that reacted with Mg (g) = mass of product – mass of Mg = 0.13g – 0.04g = 0.
09g Moles of Mg = mass of mg (g) / poor boy mass of Mg (g/ wall) = 0.04g / 24.3g/mole = 0.002moles Moles of Cl = mass of Cl (g) / molar mass of Cl (g/mole) = 0.13g / 35.5g/mole = 0.004moles The Empirical Formula = moles of each element / smallest # of the mole 0.002moles of Mg / 0.002 = 1 0.004moles of Cl / 0.002 = 2 This is a 1 to 2 ratio. The Empirical Formula is MgCl2. death: The objective of this lab was to determine what the experiential formula of magnesium chloride. through with(predicate) the calculations I corroborate made, I have resolute that the empirical formula of magnesium chloride is one magnesium atom and 2 chlorine atoms, so the formula would be MgCl2. From the information I had from the beginning, I was...If you demand to get a encompassing essay, run it on our website: Ordercustompaper.com
