Question

the diagram below is a model of two solutions. each yellow ball represents one particle of solute. solvent volume: 30 ml solvent volume: 50 ml solution a solution b which solution has a higher concentration of yellow particles? solution a solution b neither; their concentrations are the same

Explanation:

Step1: Calculate concentration formula

Concentration \( C=\frac{n}{V}\) (where \(n\) is the number of solute particles and \(V\) is the volume of the solvent). Assume the number of yellow particles (solute) in Solution A and Solution B is \(n = 6\) (counting the yellow balls).

Step2: Calculate concentration of Solution A

For Solution A, \(V_A=30\space mL\), \(C_A=\frac{6}{30}= 0.2\space particles/mL\)

Step3: Calculate concentration of Solution B

For Solution B, \(V_B = 50\space mL\), \(C_B=\frac{6}{50}=0.12\space particles/mL\)

Answer:

Solution A
