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:
