Know the Answer?

Odin Velasquez · Answer 1

Answer: 40 g.

Justification:

1) It is said that 40 g of the fertilizer-water solution is put in each container.

2) Consideriing there is not evaporation, a balance of mass tells you that the mass in each container has not changed.

3) Freezing is a physical change that does not involve exchange of mass with surroundings, so yet the mass balance indicates the each container has the same initial amount of fertilizer-water solution, which is 40g.

40 g it stays the same. (I had the same question)
