How are concentration and number of particles related?

Question

*
1 point
The concentration (mol/L) will change if the amount of solute changes
The number of particles increases without adding more solute
The number of particles does NOT have any affect on concentration

Answer 1

The correct answer is: The concentration (mol/L) will change if the amount of solute changes.

This is because concentration is defined as the amount of solute per unit volume of solution. Therefore, if you change the amount of solute, the concentration will change accordingly. The number of particles in a solution relates to the number of solute molecules or ions present, which directly affects the concentration.
