(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

How much energy is required to change one quarter of 8.0kg of water at 25°C into steam.

2. Relevant equations

I get confused to exact what equation to use to figure out the energy required.

I *think* it would be this one:

Q[itex]_{t}[/itex]=M[itex]_{water}[/itex]C[itex]_{water}[/itex][itex]\Delta[/itex]T[itex]_{water}[/itex] + .25(M[itex]_{water}[/itex])L[itex]_{f}[/itex]

3. The attempt at a solution

When I do the math, I come up with a ridulous number that makes no sense. I try and try to understand but I can't.
