Answer 1

Hi Jenna A.,

Depends on the density, doesn't it?

look up the density of water, from 4 to 100 C. Calculate the mass at those extremes. If it differs at the # significant digits given (3), then you must qualify your answer accordingly. If it is the SAME, at 3 significant digits, then that's your answer. But: why didn't I say, from 0 to 100C?
