First equation is to calculate the energy
required to bring ice temperature up to 0 degrees.
q = (Mass in grams)(Delta temp)(Cp)
q = (9800 g)(8.5 degs.)(2.06 Jg^-1c^-1)
q = 171598 J = 171.598 Kj
Next calculation is to find the energy
required to melt 9800g of ice.
q = (moles of water) (Delta H vap)
q = (9800/18 g mol^-1)x (6.02 kJ/mol)
q = 3277.5 kJ
So total energy required =
171.598 + 3277.5 = 3449.2kJ
Hope this helps
