Answer:
The answer to your question is 2.21 %
Explanation:
Data
mass of Na₂SO₄ = 10.9 g
mass of H₂O       = 482 g
Formula
Percent by mass =  x 100
 x 100
Substitution
 x 100
 x 100
Simplification and result
 x 100
 x 100
        Percent by mass = 0.022 x 100
        Percent by mass = 2.21 
 
        
                    
             
        
        
        
Explanation:
To find the amount of product that would be formed from two or more reactants, we need to follow the following steps; 
- Find the number of moles of the given reactants. 
- Then proceed to determine the limiting reactant. The limiting reactant is the one in short supply which determines the extent of the reaction. 
- Use the number of moles of the limiting reactant to find the number of moles of the product. 
- Then use this number of moles to find the mass of the product
Useful expression: 
     Mass   =  number of moles x molar mass
