A student leaves a 10.0 g ice cube in a sealed flask on the lab table. After some time, the ice melts. What is the mass of the liquid? Select one:
a. 10.0 g
b. Less than 10.0 g
c. Greater than 10.0 g
d. Not enough information

a. 10.0 g

Explanation:

Hello.

In this case, for melting phase change, which is a physical change that allow the organized molecular arrangement of solid particles to spread and turn out into the spread molecular arrangement of liquids, we must take into account that the process is undergone by the entire mass then reaching the equilibrium (after some time).

Therefore as there ware 10.0 g of ice, then 10.0 g of liquid will remain after the melting process gets carried out, thus, answer is a. 10.0 g .

Best regards.

thats a little if u want the answer just look it up on google thats what i do haha : )
