In the following reaction, what mass of magnesium sulfate is formed when magnesium reacts with excess sulfuric acid?
Step 1: Given data
of Magnesium
Step 2: Applying Stoichiometry
From the reaction, we can say that
One mole of Magnesium yields one mole of Magnesium sulphate.
Number of moles of MagnesiumNumber of moles Magnesium Sulfate
Moles of Magnesium
So, moles of Magnesium Sulfate
The molecular weight of one Magnesium Sulfate
So, the molecular weight of Magnesium Sulfate
Therefore, the molecular weight of Magnesium Sulfate when Magnesium reacts with Sulfuric acid is
