Answer : The correct option is, 5.3 grams
Explanation :
First we have to calculate the moles of and .
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 moles of react with 1 mole of
So, 0.133 moles of react with moles of
That means, in the given balanced reaction, is a limiting reagent because it limits the formation of products and is an excess reagent.
Now we have to calculate the moles of MgO.
As, 2 moles of react with 2 moles of
So, 0.133 moles of react with moles of
Now we have to calculate the mass of MgO.
Therefore, the mass maximum amount of magnesium oxide is, 5.3 grams
