∙ 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 .

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 %.
