Answer:

Explanation:
Hello,
In this case, considering that the density of a body is computed given its mass and volume:

Taking into account that the mass is 24.32 g and the volume is computed via the difference between the volume of the water with the brass and the volume of water by itself as follows:

The density of the piece of brass turns out:

This is the water cycle and the process is Evaporation.
Answer:
my teacher would let u say the density to mass is the ratio but i think everyone's different
The moles of any substance are equal to the substance's mass divided by its molar mass. Therefore, in order to calculate the moles of copper, you would divide the reacted mass by 63.55
