Of 0.605 g of magnesium hydroxide reacts with 0.800 g of sulfuric acid, what is the mass of magnesium sulfate produced?
Steps would be appreciated! Thanks (:

Mass = 0.963 g

Explanation:

Given data:

Mass of Mg(OH)₂ = 0.605 g

Mass of H₂SO₄ = 0.800 g

Mass of MgSO₄ = ?

Solution:

Chemical equation:

Mg(OH)₂  +  H₂SO₄   →    MgSO₄ + 2H₂O

First of all we will calculate the number of moles of each reactant.

Number of moles of Mg(OH)₂:

Number of moles = mass / molar mass

Number of moles = 0.605 g / 58.32 g/mol

Number of moles = 0.01 mol

Number of moles of H₂SO₄ :

Number of moles = mass / molar mass

Number of moles = 0.800g / 98.08 g/mol

Number of moles = 0.008 mol

Now we will compare the moles of MgSO₄ with  Mg(OH)₂ and  H₂SO₄  

         Mg(OH)₂         :           MgSO₄    

               1                 :               1

              0.01            :            0.01

             H₂SO₄             :           MgSO₄    

               1                      :               1

              0.008                :            0.008

The number of moles of magnesium sulfate produced by sulfuric acid are less so it will be a limiting reactant.

Mass of magnesium sulfate:

Mass = number of moles × molar mass

Mass = 0.008 mol × 120.37 g/mol

Mass = 0.963 g

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
