Question

the diagram below is a model of two solutions. each blue ball represents one particle of solute. solvent volume: 20 ml solution a solvent volume: 35 ml solution b which solution has a higher concentration of blue particles? solution a solution b neither; their concentrations are the same

Explanation:

Step1: Calculate concentration for Solution A

Concentration formula: \(C=\frac{n}{V}\) (where \(n\) is the number of solute particles and \(V\) is the volume of solvent). For Solution A, \(n = 3\), \(V=20\space mL\). So \(C_A=\frac{3}{20}= 0.15\space particles/mL\)

Step2: Calculate concentration for Solution B

For Solution B, \(n = 9\), \(V = 35\space mL\). So \(C_B=\frac{9}{35}\approx0.26\space particles/mL\)

Answer:

Solution B
