To find the percent composition of magnesium (Mg) in magnesium oxide (MgO), first determine the molar masses: magnesium has a molar mass of approximately 24.31 g/mol, and oxygen has a molar mass of about 16.00 g/mol. The molar mass of MgO is roughly 40.31 g/mol (24.31 g/mol + 16.00 g/mol). The percent composition of magnesium is then calculated as (24.31 g/mol / 40.31 g/mol) × 100%, which equals approximately 60.3%.

What is the percent composition of magnesium in MgCrO4?
To find the percent composition of magnesium in magnesium chromate (MgCrO4), first calculate the molar mass of the compound. The molar mass of magnesium (Mg) is approximately 24.31 g/mol, chromium (Cr) is about 51.996 g/mol, and oxygen (O) is about 16.00 g/mol. Thus, the molar mass of MgCrO4 is 24.31 + (2 × 51.996) + (4 × 16.00) = 200.31 g/mol. The percent composition of magnesium is calculated as (24.31 g/mol ÷ 200.31 g/mol) × 100%, which is approximately 12.13%.
What is the chemical formula for dilute magnesium hydroxide?
The chemical formula for magnesium hydroxide is Mg(OH)2. When diluted, the formula remains the same as it represents the compound's composition of one magnesium ion (Mg) bonded to two hydroxide ions (OH).
What is the percent composition for magnesium carbonate?
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.
What is the composition of (Mg) in MgO?
In magnesium oxide (MgO), magnesium (Mg) is present as a cation with a +2 charge. The composition consists of one magnesium atom combined with one oxygen atom, resulting in a 1:1 molar ratio in the compound. The molar mass of magnesium is approximately 24.31 g/mol, while that of oxygen is about 16.00 g/mol. Thus, Mg contributes about 60.3% of the total mass of MgO.

What is the percent composition of magnesium Mg in MgO?
The percent composition of magnesium (Mg) in MgO is 60%. This is because there is one magnesium atom (24.3 g/mol) and one oxygen atom (16.0 g/mol) in the formula unit MgO (40.3 g/mol), so dividing the molar mass of magnesium by the molar mass of MgO gives 0.603, or 60.3%.
What one has a higher mass percent of magnesium MgO or Mg3N2?
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%.
