12.04moles
Explanation:
Given parameters:
Number of molecules = 7.25 x 10²⁴molecules
unknown:
Number of moles = ?
Solution:
The moles of a substance is the amount of substance that contains avogadro's number of particles:
1 mole of a substance = 6.02 x 10²³
x moles of the compound will contain: ![\frac{7.25 x 10[tex]^{24}](https://tex.z-dn.net/?f=%5Cfrac%7B7.25%20x%2010%5Btex%5D%5E%7B24%7D)
}{6.02 x 10
}[/tex] = 12.04moles
This gives 12.04moles

Answer : The volume range in milliliters for the solution is 0.25 - 0.5 mL
Explanation :
We have been given that there are approximately 20 drops per milliliter of water
This information can be used as a conversion factor as 
We are using 5-10 drops of the solution.
Let us calculate milliliters in 5 drops.
Similarly, 10 drops would contain
solution.
Therefore the volume range in milliliters for the solution is 0.25 - 0.5 mL
Answer: A gas is a form of matter that lacks either a defined shape or a define volume. In other words, it fills a container and takes its shape. Any form of matter that exists as a solid or liquid also takes the form of a gas. Matter changes into a gas when temperature increases and pressure decreases.
