the diagram below is a model of two solutions. each yellow ball represents one particle of solute. solvent volume: 45 ml solvent volume: 45 ml solution a solution b which solution has a higher concentration of yellow 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 for both, and we assume volume of solute is negligible compared to solvent, so volume of solution is same for both.
Step2: Count solute particles
Solution A has 10 yellow - solute particles and Solution B has 8 yellow - solute particles.
Step3: Compare concentrations
Since volume is the same and amount of solute in Solution A is greater, Solution A has a higher concentration.
Answer:
Solution A
