the diagram below is a model of two solutions. each blue ball represents one particle of solute. solvent volume: 45 ml solvent volume: 40 ml solution a solution b which solution has a higher concentration of blue particles? solution a solution b neither; their concentrations are the same

the diagram below is a model of two solutions. each blue ball represents one particle of solute. solvent volume: 45 ml solvent volume: 40 ml solution a solution b which solution has a higher concentration of blue particles? solution a solution b neither; their concentrations are the same

Answer

Explanation:

Step1: Count solute particles

Solution A has 7 solute particles, Solution B has 7 solute particles.

Step2: Calculate concentration formula

Concentration = $\frac{\text{Amount of solute}}{\text{Volume of solvent}}$. For Solution A, concentration $C_A=\frac{7}{45}$; for Solution B, concentration $C_B = \frac{7}{40}$.

Step3: Compare concentrations

Since $\frac{7}{40}>\frac{7}{45}$ (when the numerators are the same, the fraction with the smaller denominator is larger), Solution B has a higher concentration.

Answer:

Solution B
