Question

A 10.0-g sample of magnesium reacts with oxygen to form 16.6 g of magnesium oxide. How many grams of oxygen reacted?

Answer 1

6.6 grams of oxygen reacted with magnesium to give magnesium oxide.

What is law of conservation of mass?

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+O₂$\rightarrow$2 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.
