    You need some constants 

     ==  The specific heat of ICE ( it is not the same as liquid water)  

      ==  The specific heat of liquid water ( 4.184 J/g deg C)

     ==  the latent heat of fusion of water

    ===================================

      Q = mc(delta T)  <<<  do this calc. for ice  ... delta T will be (0 - -15.2)

      Q = m Lf  <<< melting ice

      Q = mc(delta T)   <<<  this time for liquid ice  ... delta T will be (35.6 - 0)

      final answer .. add all the above
