Hello there!
In this case, according to the given atoms of aluminum, it is possible for us to calculate the mass via the Avogadro's number and its atomic mass of 27.0 g/mol:
Noe, given the density of the Al, we can calculate the volume as shown below:
Best regards!
Answer:
Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.
In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible. In contrast, the molecules in liquids are very close together, with essentially no empty space between them

Answer:
the attraction water molecules have to other surfaces
Explanation:
Adhesion is defined as the attractive forces between unlike substances, e.g water moving up a capillary tube.
Adhesion is the tendency of dissimilar particles or surfaces to cling to one another(Wikipedia).
So, what we mean by adhesion in this context, is the attraction water molecules to other surfaces.

Answer : The temperature on the Fahrenheit scale was,
Explanation :
The conversion used for the temperature from degree centigrade to Fahrenheit is:
where,
= temperature in Fahrenheit
= temperature in centigrade
As we are given the temperature in degree centigrade is, 45
Now we have to determine the temperature in Fahrenheit.
Therefore, the temperature on the Fahrenheit scale was,
