Question

the diagram below is a model of two solutions. each yellow ball represents one particle of solute. solvent volume: 45 ml solution a solvent volume: 40 ml 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 8 yellow balls (solute particles), Solution B has 7 yellow balls.

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: \(C_A=\frac{8}{45}\approx0.178\). For Solution B: \(C_B = \frac{7}{40}=0.175\).

Answer:

Solution A
