Answer : The mass of lithium hypochlorite are, 34.7 grams.
Explanation : Given,
Moles of  = 0.594 g
 = 0.594 g
Molar mass of  = 58.4 g/mol
 = 58.4 g/mol
Expression used :
 
Now put all the given values in this expression, we get:
 
 
Therefore, the mass of lithium hypochlorite are, 34.7 grams.
 
        
             
        
        
        
Explanation:
molarity = no. of moles of solute/solution in litres
molarity =0.202/7.98
=0.025 M
 
        
             
        
        
        
For the first one.. the Reactant side is Zn+2HCl produces Zncl2 and H2... and it is balanced too
