Question

the diagram below is a model of two solutions. each purple ball represents one particle of solute.solvent volume: 30 mlsolution asolvent volume: 50 mlsolution bwhich solution has a higher concentration of purple particles?solution asolution bneither; their concentrations are the same

Explanation:

Step1: Count solute particles for each solution

Solution A: 3 particles; Solution B: 15 particles

Step2: Calculate concentration (particles/mL)

Concentration of A: $\frac{3}{30} = 0.1$ particles/mL
Concentration of B: $\frac{15}{50} = 0.3$ particles/mL

Step3: Compare the two concentrations

$0.3 > 0.1$, so Solution B has higher concentration.

Answer:

Solution B
