How do you find the mole ratio of magnesium to oxygen?
Calculate the mole ratio of magnesium to oxygen. To do this, divide the moles of magnesium by the moles of oxygen. Express the result to the correct number of significant figures.
Read everything about it here. In respect to this, what is the mole ratio of magnesium to oxygen?
The ratio should be close to 1:1 as the formula of magnesium oxide is MgO. This would suggest a formula of MgO, which is the correct formula. Students will need the mass of the magnesium and the mass of oxygen which has combined with it.
Likewise, how do you find the mole ratio?
- Start with the number of grams of each element, given in the problem.
- Convert the mass of each element to moles using the molar mass from the periodic table.
- Divide each mole value by the smallest number of moles calculated.
- Round to the nearest whole number. This is the mole ratio of the elements and is.
Similarly, it is asked, how do you calculate moles of magnesium?
Calculating the mass of reactants
- Magnesium reacts with oxygen to produce magnesium oxide:
- 2Mg(s) + O2(g) 2MgO(s)
- Calculate the mass of magnesium needed to produce 12.1g of magnesium oxide.
- (Relative masses: Mg = 24.3, MgO = 40.3)
- number of moles of MgO =
- =
- = 0.300 mol.
How many grams are in one mole of magnesium?
However, one mole of magnesium weighs 24.31 g.
