Answer:

#168,000J# or #168kJ#

Explanation:

specific latent heat of fusion: the amount of energy required to heat 1kg of a solid to a liquid or 1kg of a liquid to a solid, without changing the object's temperature.

this is denoted as #L#.

the equation relating energy, mass, and specific latent heat of fusion is #E=mL#.

note: #E# is in joules, #m# in kilograms and #L# in J/kg.

information given in question:
#m=500g=0.5kg#

the specific latent heat of ice is #336,000#J/kg.

using this, #E=0.5#kg#*336,000#J/kg
#=168,000J#
or #168kJ#
