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 is the percent composition of magnesium (mg) in mg0?
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 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%.
What is the percent composition of magnesium (mg) on MgO?

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 percent composition of each element in Mg3(PO4)2?
The percent composition of each element in Mg3(PO¬4)2 is: Magnesium (Mg) = 24.6% Phosphorus (P) = 21.4% Oxygen (O) = 54.0% (Note: These percentages are approximate and rounded)
What is the percent composition of a compound containing 32.0 g of bromine and 4.9 g of magnesium?
Total mass of MgBr2- 36.9 g Mass of Br 32.0 / total mass 36.9 = .867 = 86.7% Mass of Mg 4.9 / 36.9 = .133 = 13.3% There is 86.7% of Bromine and 13.3% of Magnesium in the compound MgBr2
What is the percent composition of magnesium?
The percent composition of magnesium in a compound would depend on the specific compound. However, if you're referring to the naturally occurring magnesium element, it makes up about 12% of the Earth's crust by mass.
What is the percent compostition of magnesium chlorate?
Magnesium chlorate has a percent composition of approximately 16.4% magnesium, 21.8% chlorine, and 61.8% oxygen by mass.
What is the percent composition of CI in MgCI2?
To find the percent composition of chlorine (Cl) in magnesium chloride (MgCl₂), first calculate the molar mass of MgCl₂. The molar mass of magnesium (Mg) is approximately 24.31 g/mol, and that of chlorine (Cl) is about 35.45 g/mol. Thus, the molar mass of MgCl₂ is 24.31 + (2 × 35.45) = 95.21 g/mol. The percent composition of Cl is then calculated as (2 × 35.45 / 95.21) × 100%, which is approximately 74.4%.
