here we have to compute this: (heat of fusion of iron) times (mass of iron)

5. anonymous

okay so 1000 times _____ ? not sure what to multiply it by :/

time the heat of fusion for iron

7. Michele_Laino

${10^3} \times 2.66 \times {10^5} = ...Joules$

oh okie! so we get this? 266000000? so our solution is choice D?

9. Michele_Laino

that's right!
