Answer:

120g of magnesium oxide is formed

Explanation:

the balanced equation is

2Mg+O₂ ⇒ 2MgO

by atomic mass the equation is

48g of magnesium gives 80g of magnesium oxide(ignore Oxygen)

in the question

72 g of magnesium gives X g of magnesium dioxide

so through variation method

72/48 * 80 = 120

therefore 120g of magnesium dioxide is formed
