It was a physics test question I had and don't know how to set it up. I know
Miceoriginal+6g= Micenew + Mwater
Other then that I don't know how to do it/set it up. Any help would be nice ty.

Water is more dense than ice so if a lot of ice melts to water, then mass should grow. To say it can't be reached is not an option.

If this can not be done then why would there be an answer of like 3.68c10^8 kg?

Start with 6 grams of ice. Melt it. You have 6 grams of water, barring evaporation. You have only got half the problem so you cannot answer it and we have no chance.

melting is a physical change. Therefore, no matter how much you melt it, you will never acheive a result where the amount of substance changes. The law of conservation of mass states that mass cannot be created ordestroyed. ( the only exception to this is in nuclear reactions inside the sun, or inside either a fission or fusion reaction inside a nuclear weapon. E=mc^2 states that a very small amount of energy can be transfered into energy) whith this taken into consideration, it would be theoretically possible for someone to make ice undergo a nuclear reaction, and if certain fragments of the oxygen molecule were toaccelerate to the speed of light, they would become pure energy.In that way, although impracticle and needless to say far beyond anything humans will ever be capable of, it theoretically might be possible to, by heating the ice to an insane temperature, and in the process melt the ice, to make the ice loose any amount of mass. eventhough the mass is still energy, it does not have a definte physical composition. it is theorized that energy in the form of waves contains both characteristics of energy and waves, it is not mass. What I am trying to say through all this confusing stuff, is that it is theoretically possible to loose mass (as has been observed in nuclear fission and fusion reactons)

Melting ice or freezing water won't change the mass. The volume will change but not the mass.

Melting ice cannot gain mass
