∙ 11y agoweigh the magnesium and container before the experiment. then after, reweigh the everything and subtract the weight of magnesium and the container from the weight after the experiment. you can then calculate the percentage by timsing the answer by 100

∙ 9y agoFirst we obtain some figures.Atomic Mass of magnesium, Mg is 24.3
Atomic mass of oxygen, O is 16.0
The unit formula mass of magnesium oxide, MgO would therefore be 24.3 + 16.0 = 40.3
So, percentage composition (by mass) of Mg in MgO = 24.3/40.3 x 100 = 60.3%
Wiki User
∙ 12y agoTake the mass of Mg and divide it by the mass of MgO which should be 60.31% if I did my math right.
Wiki User
∙ 11y ago40 Percent.
molecular mass of MgO = 24 + 16 = 40
percentage of oxygen = 100 x 16/40 = 40 .

If Mg reacts with O the compound is MgO?
Yes, when magnesium (Mg) reacts with oxygen (O), it forms magnesium oxide (MgO) as the compound.
What is the chemical formula for Magnesium Oxide?
The chemical formula for Magnesium Oxide is MgO. It is composed of one magnesium atom and one oxygen atom.
When 4.00g of magnesium burns the theoretical yield of magnesium oxide is?
2 Mg (s) + O2 (g) → 2 MgO (s)4.00mg x 1 mol Mg/24.305 x 2 mol MgO/2 mol Mg x 40.305g MgO/1 mol MgO==6.63g4.00g- Given24.305g- Atomic Mass of Magnesium40.305g- Atomic Mass of Magnesium Oxide
Symbol equation for magnesium?
The symbol equation for the reaction of magnesium with oxygen to form magnesium oxide is: 2Mg + O2 -> 2MgO
What is the balanced symbol equation for copper sulphate and Magnesium?
Half equations ?? The chemical formula of magnesium oxide is 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 is the percent composition of magnesium mg in mg?
mg
If some magnesium oxide had escaped from The Crucible would the percentage composition calculation of magnesium be too high or too low?
The percent of Mg calculated will be too high. Let's say that you reacted 1.00 g of Mg and made some MgO, but so much MgO escaped as smoke that only 1.00 g of MgO was left. You would then conclude from the numbers that the mass of O in the MgO was zero! This would lead you to conclude that the percent of Mg in the MgO was 100 %, which is silly and clearly in error. Although this is an extreme example, it illustrates that the loss of MgO as smoke from the crucible leads to a percent of Mg (calculated) that is above the expected 60.3 %.
What is the atomic symbol for magnesium?
The atomic symbol for magnesium is Mg.
What is the chemical equation for Magnesium Oxide with Hydrogen?
The chemical equation for the reaction between magnesium oxide and hydrogen is: MgO + H2 -> Mg + H2O
If Mg reacts with O the compound is MgO?
Yes, when magnesium (Mg) reacts with oxygen (O), it forms magnesium oxide (MgO) as the compound.
What is the chemical formula for Magnesium Oxide?
The chemical formula for Magnesium Oxide is MgO. It is composed of one magnesium atom and one oxygen atom.
When added to water would MgO produce a base?
Yes, when magnesium oxide (MgO) is added to water, it will produce magnesium hydroxide (Mg(OH)2), which is a base. MgO reacts with water to form Mg(OH)2 by accepting a proton from water molecules.
Is mgo a metal?
Yes, MgO is a compound formed by magnesium (Mg) and oxygen (O) atoms. Magnesium is a metal, but in MgO it is in its oxidized form as an oxide.
Magnesium and oxygen formula?
The formula for magnesium oxide is MgO. This compound forms when magnesium reacts with oxygen.
Symbol equation for magnesium oxide?
Mg + O ----> MgO
What is the chemical formula for magnesum oxide?
The chemical formula for magnesium oxide is MgO, where Mg represents magnesium and O represents oxygen.
