How is a mole related to concentration?
2 answers:
A mole is related to concentration in a solution as in option 2: The number of particles of solute in a solution is measured in moles.
The Avogadro's number is defined as:
A = 6.022x10²³ mol⁻¹
Hence, in 1 mole we have 6.022x10²³ particles, or atoms, or molecules, or other.
Let's evaluate every option.
1. The saturation point of a solution is measure in moles. False
The saturation point indicates how is the solubility of a solute in a solution. Its units are given in the amount of solute (mol, g, or L) per unit of solution (L or g).
2. The number of particles of solute in a solution is measured in moles. True
As we said above, in 1 mole we have 6.022x10²³ particles of solute in a solution.
3. The volume of particles of solute in a solution is measured in moles. False
The volume of a solution is measured in liters (L) or m³, not in moles.
4. The mass of the solute in a solution is measured in moles. False
The mass is measured in kilogram (kg), not in moles.
Therefore, the correct option is 2: The number of particles of solute in a solution is measured in moles.

I believe "h" stands for hecta-, which means "one hundred."
I will convert from g to hg (divide by 100), then from mL to L (multiply by 1000).
