Question

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

Explanation:

Step1: Count the number of solute particles

Solution A has 10 pink balls (solute particles), Solution B has 8 pink balls (solute particles).

Step2: Calculate the concentration formula

Concentration \(C=\frac{n}{V}\) (where \(n\) is the amount of solute, \(V\) is the volume of solvent). For Solution A: \(C_A=\frac{10}{50}= 0.2\) particles/mL. For Solution B: \(C_B=\frac{8}{35}\approx0.23\) particles/mL.

Answer:

Solution B
