the diagram below is a model of two solutions. each blue ball represents one particle of solute. solvent volume: 50 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: Calculate concentration of Solution A
Concentration formula: $C=\frac{n}{V}$ (where $n$ is the number of solute particles, $V$ is the volume of solvent). For Solution A, $n = 5$, $V=50\space mL$. So $C_A=\frac{5}{50}= 0.1\space particles/mL$.
Step2: Calculate concentration of Solution B
For Solution B, $n = 4$, $V = 40\space mL$. So $C_B=\frac{4}{40}=0.1\space particles/mL$.
Answer:
neither; their concentrations are the same
