What mass of oxygen gas reacted with the magnesium ?

1.10 g O2
You can get to this two ways.
1) You can subtract the mass of the crucible + Mg from the Mass of the crucible + MgO
2) Calculate the mass of Mg (subtract mass of empty crucible from mass of crucible + Mg)
Then calculate the mass of MgO (Subtract mass of empty crucible from mass of crucible + MgO)
Finally, subtract mass of Mg from mass of MgO
