Final answer:
When 60 grams of ice melts, 60 grams of liquid water are produced.
Step-by-step explanation:
To determine how many grams of water are produced when ice melts, we need to use the concept of conservation of mass. When ice melts, it is changing from the solid state to the liquid state, but the total mass remains the same. Since the mass of the ice is given as 60 grams, the mass of the liquid water produced will also be 60 grams.
