Calculating Original Mass of Ice at 0 Degrees C

[sanphy]

The question is:
Ice at 0 degree C turns into Water at 0 degree C and thus gains 1 Kg of mass. What is the original mass of ice?

Use E_w-E_i=(m_w-m_i)c^2=m_i*L, where L is the specific latent heat.

What has this to do with nuclear and particle physics?

Let's just say that if you don't help sanphy, he'll go nuclear and physically smash you to particles.

Well this is indeed not a nuclear or particle physics question and is a mass-energy question.
I tried to solve but the mass comes out as 2.67 * 10^11 kg.
I think this could be correct.
