Question

the diagram below is a model of two solutions. each yellow ball represents one particle of solute. solvent volume: 50 ml solvent volume: 50 ml solution a solution b which solution has a higher concentration of yellow particles? solution a solution b neither; their concentrations are the same

Explanation:

Step1: Count the number of solute particles

Solution A has 12 yellow particles (solute). Solution B has 12 yellow particles (solute).

Step2: Recall the formula for concentration

Concentration \(C=\frac{\text{Amount of solute}}{\text{Volume of solvent}}\). Here, volume of solvent for both \(A\) and \(B\) is \(50\space mL\).

Step3: Calculate the concentration for both solutions

For solution \(A\), \(C_A=\frac{12}{50}\). For solution \(B\), \(C_B = \frac{12}{50}\)

Answer:

neither; their concentrations are the same
