One type of sunburn occurs on exposure to UV light with a wavelength in the vicinity of 325 nm. What is the energy of a mole of 
these photons?
       
      
                
     
    
    
    
    
    1 answer:
            
              
              
                
                
Answer: Energy of a mole of these photons is  
   
Explanation:
The relationship between wavelength and energy of the wave for 1 mole follows the equation:
 
E= energy
N= avogadros number =
 = wavelength of the wave  =
 = wavelength of the wave  = 
    
h = Planck's constant  =  
c = speed of light =  
 
 
   
Thus the energy of a mole of these photons is
