Due to the oxygen from the air combining with the magnesium to form magnesium oxide, or MgO, the mass has increased.

The total mass of the magnesium increases when it is heated because magnesium combines with oxygen to generate magnesium oxide ( so it supported the hypothesis). It is oxygen that has caused the increased bulk.

Magnesium creates light intense enough to briefly impair your vision when it combines with oxygen. Magnesium burns so brightly because a lot of heat is released during the process. This exothermic process causes magnesium to donate two electrons to oxygen, resulting in the formation of powdered magnesium oxide (MgO).

Therefore, Due to the oxygen from the air combining with the magnesium to form magnesium oxide, or MgO, the mass has increased and hence the other 1.95 grams has come from oxygen.
