Magnesium: Chlorine and Hydrogen Moles

ATOMIC WEIGHT OF MAGNESIUM lab Introduction The main purpose for this essayal lab is to determine the nuclear weight of magnesium, as well as an underlying purpose in determining the relationship between molees evolved and consumed. This can be demonstrated by measuring the hydrogen gas evolved by performing a chemic experiment when hydrochloric acid reacts with the magnesium. The formulated reaction includes Mg + 2HCl H2 + Mg2+(aq) + 2Cl- (aq)The major findings change to the experiment is being able to determine and distinguish what moles have evolved therefrom being the hydrogen moles evolved allowing the magnesium to be consumed within the reaction. Procedure timbre 1 Obtain a 600 mL beaker, and add 300 mL of water. Step 2 supply 30 mL of HCl (2M) to the beaker, and stir. Step 3. Add 10 mg of magnesium metal to the beaker. Step 4. Allow the hydrogen gas to evolve. All of the magnesium should be consumed. Step 5. Record the metre of hydrogen gas that has evolved using t he chemical property dialog.Observations and Results Moles of hydrogen evolved 0. 000411 (4. 11 x 10-4th) moles of H2 evolved Calculated atomic weight of magnesium Weight of Mg /moles of H2 evolved 24. 305g/mol / 0. 000411 = 59,136. 25 g/mol of Mg As I keep with my experiment I came across a few observations that are weighty to bring to attention. As I added 10 mg of magnesium to the beaker of HCl, a shaded area appeared at the bottom of the beaker. Directly after, bubbles formed in the kindred beaker thus indicating the Mg was being consumed. DiscussionThe moles of hydrogen gas that have evolved during the experiment resulted in 0. 000411. The calculated atomic weight of magnesium is determined by the formula of atomic weight of Mg (in grams)=weight of Mg consumed (in grams) / moles of H2 evolved, then the equation should be similar to this 24. 305g/mol / 0. 000411 = 59,136. 25 g/mol of Mg. This experiment is clearly a branch of stoichiometry because a reaction takes inject an d it is the duty of the student to calculate or determine the relative atomic mass of Magnesium.
