Assuming you meant ice or solid H2O:
$q = m H_{f}$ $q = mH_f$

Explanation:

q is the symbol for heat energy
m is the mass of ice, $m = 500 g$ $m= 500 g$
$H_{f} = 334 \frac{J}{g}$ $H_f = 334J/g$ for $H_{2} O$ $H_2O$
$q = (500 g) (334 \frac{J}{g})$ $q= (500g)(334J/g)$
$q = 167000 J$ $q=167000J$ or $167 k J$ $167 kJ$
