If you have 45cm3 of an acid reacting with zinc, and the difference of mass after the reaction is eg 32g, when calculating q=mc(delta)t, which value do you use? I did an experiment on this and used the difference in mass but i think it's wrong? If so though, what would be the point of finding this value if it isn't being used?

the mass you use in q = m x c x deltaT is the mass of the water (or solution) which is being heated
