Question

how is a mole related to concentration? (1 point)
the volume of particles of solute in a solution is measured in moles.
the number of particles of solute in a solution is measured in moles.
the saturation point of a solution is measured in moles.
the mass of the solute in a solution is measured in moles.

Explanation:

A mole is a unit that measures the amount of a substance. In the context of solutions, it measures the number of particles (atoms, molecules, ions etc.) of solute. Concentration is often expressed in terms of moles per unit volume (e.g., molarity which is moles of solute per liter of solution). So, the number of particles of solute is measured in moles which is related to how concentrated a solution is.

Answer:

The number of particles of solute in a solution is measured in moles.
