PLEASE HELP ASAP WILL GIVE BRAINLIEST!! 2. Subtract the mass of the crucible and lid (row 1 in the chart) from the total mass of Mg, crucible, and lid (row 2 in the chart) to find the mass of magnesium for each trial.

• Trial 1:

• Trial 2:

3. Subtract the mass of the crucible and lid (row 1 in the chart) from the total mass of MgO, crucible, and lid (row 3 in the chart) to find the mass of magnesium oxide for each trial. This is the actual yield of magnesium oxide for each trial.

• Trial 1:

• Trial 2:

4. Magnesium is the limiting reactant in this experiment. Calculate the theoretical yield of MgO for each trial.

• Trial 1:

• Trial 2:

5. Determine the percent yield of MgO for your experiment for each trial.

• Trial 1:

• Trial 2:

6. Determine the average percent yield of MgO for the two trials.
