the diagram below is a model of two solutions. each green ball represents one particle of solute. solvent volume: 35 ml solvent volume: 35 ml solution a solution b which solution has a higher concentration of green 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. Assume negligible volume - change on adding solute, so volume of solution is same.
Step2: Count solute particles
Solution A has 8 green - solute particles and Solution B has 6 green - solute particles.
Step3: Compare concentrations
Since volume is the same and amount of solute in Solution A is greater than in Solution B, Solution A has a higher concentration.
Answer:
Solution A
