If you have some mass of iron and some mass of water, and both are in zero degrees Celsius, and you use the same amount of energy to heat up both into 100 degrees Celsius, which were the masses of the water and the iron?

At least 1

Not homework. I just found the question interesting.

About 3.50

Infinite answers possible. The ratio of the masses has a unique solution. Also the question is ambiguous because depending on atmospheric pressure 100C could be just below boiling point or just above which would use less energy, but the metal would not change state (I'm assuming it's a human survivable pressure).

Yeah it was a kind of trick question. But like you said you could still solve the relationship between the masses, like if the masses are X and Y, you would could have an equation like X = Z*Y where the Z would have a unique value. And I guess you could assume standard temperature and pressure if those are not otherwise specified.

specific heat of water: 4.18 J/g/C
specific heat of iron: 0.45 J/g/C
ratio of water to iron is .45/4.18
