6.6 grams of oxygen reacted with magnesium to give magnesium oxide.
<h3>What is law of conservation of mass?</h3>
When a chemical reaction takes place the total mass of reactants is always equal to the mass of products.As in a chemical reaction the atoms are neither created nor destroyed rather they rearrange themselves.
The reaction between magnesium and oxygen is as follows,
2 Mg+O₂2 MgO
According to the question, 10 g of magnesium is utilized to produce 16.6 g of magnesium oxide.In order to find mass of oxygen utilized ,
mass of oxygen=mass of magnesium oxide-mass of magnesium
substituting the given data,
mass of oxygen=16.6-10=6.6 g
Thus, 6.6 grams oxygen reacted to produce 16.6 grams of magnesium oxide.
