What is the mass of oxygen when it reacts with 12g of magnesium?

Mass magnesium oxide = 3.78 g. So mass oxygen = 1.39 g.

What mass of magnesium oxide is formed when 24g of magnesium reacts with oxygen?

40 g
We are told that 24 g of Mg produces 40 g of MgO when it reacts with 16 g of oxygen.

What mass of magnesium oxide is formed when 120 gram of magnesium is burnt in excess of oxygen?

What mass of magnesium oxide is produced when 60g of magnesium is burned in air?

60g of Mg makes 1.66 x 60 = 100g of MgO.

What mass of magnesium oxide is formed by the complete combustion of 24g of magnesium?

40 g of magnesium oxide is produced when 24g of magnes is burnt.

What mass of magnesium oxide is formed if magnesium is burnt in oxygen?

As per the above reaction, Two molecules of magnesium form two molecules of magnesium oxide. And we know, the mass of magnesium is $24g$ and that of oxygen is $16g$. So, the mass of magnesium oxide i.e. MgO will be $24+16=40g$.

What compound is formed on burning magnesium in air?

Magnesium Oxide
When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. A compound is a material in which atoms of different elements are bonded to one another. Oxygen and magnesium combine in a chemical reaction to form this compound.

How many grams of magnesium oxide is produced when 24 grams of magnesium is completely burnt in oxygen?

And we know, the mass of magnesium is $24g$ and that of oxygen is $16g$. So, the mass of magnesium oxide i.e. MgO will be $24+16=40g$. That means, $24g$ of magnesium will form $40g$ of magnesium oxide.

What mass of magnesium oxide is produced?

6.08 g of magnesium reacts with 4.00 g oxygen to produce magnesium oxide, MgO.

What mass of magnesium oxide is formed in this reaction?

In your case, magnesium metal and oxygen gas are the reactants and magnesium oxide is the product. You know that 10.0 g of magnesium take part in this reaction and that 16.6 g of magnesium oxide are produced.
