Magnesium is a metal element. Atomic mass of it is 24.
When magnesium is heated in air, it forms magnesium oxide and so the total mass increases.
magnesium thiotellurite
Magnesium's mass increases as it becomes magnesium oxide.
Magnesium nitride (Mg3N2) has a higher percentage composition of magnesium than magnesium oxide (MgO) does. The percentage composition of magnesium in magnesium nitride is 72.2% and the percentage composition of magnesium in magnesium oxide is 60.3%.

The Atomic Mass of Magnesium is 24, the RAM (relative atomic mass) is 24.305.
The gram formula mass of the less hydrated stable form of magnesium nitrate, Mg(NO3)2.2 H2O, is 184.35. This formula shows that each formula unit contains one magnesium atom. The gram atomic mass of magnesium is 24.305. Therefore, the percentage by mass of magnesium in this magnesium nitrate dihydrate is 100(24.305/184.35) or 13.038 %, to the justified number of significant digits.
Magnesium is a meta element. Atomic mass of it is 24.

You take the mass and divide it by the total mass of the element. Magnesium by itself is 100%.
