Question

the diagram below is a model of two solutions. each green ball represents one particle of solute. solvent volume: 25 ml solution a solvent volume: 30 ml solution b which solution has a higher concentration of green particles? solution a solution b neither

Explanation:

Step1: Define Concentration Formula

Concentration (C) is calculated as the number of solute particles (n) divided by the volume of solvent (V), so \( C = \frac{n}{V} \).

Step2: Calculate Concentration for Solution A

Solution A has \( n_A = 2 \) particles and \( V_A = 25 \, \text{mL} \).
\( C_A = \frac{2}{25} = 0.08 \, \text{particles/mL} \).

Step3: Calculate Concentration for Solution B

Solution B has \( n_B = 2 \) particles and \( V_B = 30 \, \text{mL} \).
\( C_B = \frac{2}{30} \approx 0.0667 \, \text{particles/mL} \).

Step4: Compare Concentrations

Since \( 0.08 > 0.0667 \), \( C_A > C_B \).

Answer:

Solution A
