Question

the diagram below is a model of two solutions. each purple ball represents one particle of solute. solvent volume: 30 ml solvent volume: 45 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 3 solute particles and the solvent volume is 30 mL. So the concentration \(C_A=\frac{3}{30}=\frac{1}{10} = 0.1\) particles per mL.

Step2: Calculate the concentration of Solution B

For Solution B, there are 10 solute particles and the solvent volume is 45 mL. So the concentration \(C_B=\frac{10}{45}=\frac{2}{9}\approx0.22\) particles per mL.

Answer:

Solution B
