Calculate amount of energy needed to completely vaporize a 50g piece of 20 degree C silver

melting point 1064 C
L(f) = 64KJ/Kg

Boiling point 2856C
L(v) = 1645 KJ/Kg
c= 0.13KJ/Kg degrees C

I'm thinking I balance each side to equal each other but I'm not dure-I've done specific heat calcs with water-Could you please just tell me how to set it up
Thank you
