The four elements that make up 95 percent of the Earth's mass are oxygen, silicon, iron, and magnesium. These elements are abundant in the Earth's crust and core, contributing to its overall composition.
To calculate the percentage of magnesium by mass in a compound, divide the mass of magnesium by the total mass of the compound, then multiply by 100. Percentage of magnesium by mass = (mass of magnesium / total mass of compound) * 100.
Magnesium makes up about 2% of the Earth's crust by weight, making it the eighth most abundant element.
To find the mass percent of oxygen in the compound, first calculate the total mass of the compound by adding the masses of magnesium and oxygen: 14.5 g + 3.5 g = 18.0 g. Then, use the formula for mass percent: (mass of oxygen / total mass) × 100%. Thus, the mass percent of oxygen is (3.5 g / 18.0 g) × 100% ≈ 19.44%.
oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and 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.
The percent (by volume) of the earth crust is made up of magnesium is 0.33 percent on Page 1 of the ESRT Packet

Magnesium makes up about 2% of the Earth's crust by weight, making it the eighth most abundant element.
The moon's crust composition is similar to the Earth's, but the moon's mantle contains a higher amount of iron. While the moon's crust is composed of 43 percent oxygen, 20 percent silicon, 19 percent magnesium, 10 percent iron, and trace amounts of other elements. The Earth's crust is made up of 46.6 percent oxygen, 27.7 percent silicon, 8.1 percent aluminum, 5.1 percent of iron, 2.1 percent magnesium, and other elements.
Magnesium chlorate has a percent composition of approximately 16.4% magnesium, 21.8% chlorine, and 61.8% oxygen by mass.
To find the mass percent of oxygen in the compound, first calculate the total mass of the compound by adding the masses of magnesium and oxygen: 14.5 g + 3.5 g = 18.0 g. Then, use the formula for mass percent: (mass of oxygen / total mass) × 100%. Thus, the mass percent of oxygen is (3.5 g / 18.0 g) × 100% ≈ 19.44%.

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%.
