Question

the diagram below is a model of two solutions. each yellow ball represents one particle of solute. 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 6 yellow balls (solute particles), Solution B has 3 yellow balls.

Step2: Calculate the concentration formula

Concentration \(C=\frac{\text{amount of solute}}{\text{volume of solvent}}\). For Solution A: \(C_A = \frac{6}{50}= 0.12\) (particles per mL). For Solution B: \(C_B=\frac{3}{30}=0.1\) (particles per mL).

Answer:

Solution A
