(50.0g)(355j/g)=17750 joules You're using (g)(Heat of fusion)=change in heat, and the popsicle's (or ice's) Heat of fusion is 355 Answer with significant figures and conversion to kilojoules comes out to be 17.8KJ 1000 Joules= 1 Kj, so move the decimal over 3. There are 3 sig figs in 50.0 and 355 so the answer needs 3 sig figs.
