I believe it would weigh less if it’s blown up with helium because helium is lighter than air
M=7M(H₂O)
M=7*18.015 g/mol = 126.105 g/mol
6.02 times 10 to the 23 power, which is Avogadros number
The answer to this is Drinking Waer

Explanation:
The water in the beaker is described to be in a liquid state of matter. Its temperature decreases from 50°C to 10°C when placed in a freezer by Kiley. This means that heat is gradually being lost as the liquid water undergoes freezing into a solid state.
When water in a liquid state is freezed, it's molecules, which were moving more freely begin to move closer together because the speed at which the particles in the liquid state moved has been reduced.
