the diagram below is a model of two solutions. each pink ball represents one particle of solute. solvent volume: 30 ml solvent volume: 30 ml solution a solution b which solution has a higher concentration of pink particles? solution a solution b neither; their concentrations are the same
Answer
Explanation:
Step1: Recall concentration formula
Concentration = $\frac{\text{Amount of solute}}{\text{Volume of solution}}$. Here volume of solvent is same ($30$ mL) and no information about additional volume - so assume volume of solution is same for both.
Step2: Count solute particles
Solution A has 5 pink - solute particles. Solution B has 5 pink - solute particles.
Step3: Compare concentrations
Since amount of solute and volume of solution are the same for both, their concentrations are equal.
Answer:
neither; their concentrations are the same
