The energy would increase
b) increase kinetic energy
        
             
        
        
        
Explanation:
First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
 
        
                    
             
        
        
        
Answer:
1250N
Explanation:
This question is based on pascal's Law.
So By Pascal's Law
  =  
therefore  =force on input piston =25N
                   = Force or weight on output person.
therefore after putting the values we get,
 = (25x 1500)/30
     =1250N
