H2SO3 or sulfurous acid is actually a strong acid. We know
for a fact that strong acids completely dissociate into its component ions in a
solution, that is:
 
<span>H2SO3 -->  2H+  +  SO3-</span>
 
<span>So from the equation above, there are 2 moles of H+</span>
 
        
             
        
        
        
The student originally has 252 grams of water in this experiment. 
LAW OF CONSERVATION OF MASS:
- The law of conservation of mass explains that matter (mass) can neither be created nor destroyed but can be changed from one form to another. 
- This means that in a chemical reaction, the sum of the masses of the reactants must equate to the total mass of product(s). 
- According to this question, a student conducts an experiment to separate water into hydrogen and oxygen. The student collects 28.0 g of hydrogen and 224.0 g of oxygen. 
- Since hydrogen and oxygen are the constituent elements of water, the sum of their masses must equate the mass of water. 
- Therefore, 224g of oxygen + 28g of hydrogen = 252g of water.
