Question

the diagram below is a model of two solutions. each purple ball represents one particle of solute. solvent volume: 35 ml solvent volume: 50 ml solution a solution b which solution has a higher concentration of purple particles? solution a solution b neither; their concentrations are the same

Explanation:

Step1: Calculate the concentration of Solution A

Concentration is calculated as the number of solute particles divided by the volume of the solvent. For Solution A, there are 5 purple balls (solute particles) and the solvent volume is 35 mL. So the concentration \(C_A=\frac{5}{35}=\frac{1}{7}\approx0.143\) particles per mL.

Step2: Calculate the concentration of Solution B

For Solution B, there are 5 purple balls (solute particles) and the solvent volume is 50 mL. So the concentration \(C_B = \frac{5}{50}=\frac{1}{10}=0.1\) particles per mL.

Answer:

Solution A
