How many kilojoules of heat are required to melt a 10.0 g popsicle at 0 degress C? Assume the popsicle has the same molar mass and heat of fusion as water.
Could someone tell me what equation to use to solve this or the steps?
Thank You.

1. q = mass x heat fusion.

2. 1) Convert H2O to moles
10.0g x (1 mol/18.02 g (the molar mass of water)) = .555 mol
2) Convert moles to kJ by multiplying by the heat of fusion
.555 moles x (6.01kJ/1mol) = 3.34 kJ
