Question

A cube of ice melts in a beaker to form 10 g of water. What is the best estimate of the mass of the ice cube?

Group of answer choices

15 g

10 g

5 g

2 g

Answer 1

When a cube of ice melts, it transforms into an equivalent mass of water. This means that the mass of the ice cube before it melts would be equal to the mass of the water it forms after melting.

Therefore, if the cube of ice melts to form 10 g of water, the best estimate of the mass of the ice cube is **10 g**.

So, the correct answer is:

**10 g**
