the diagram below is a model of two solutions. each ball represents one particle of solute. which solution has a higher concentration of pink particles? solution a solution b neither; their concentrations are the same
Answer
Explanation:
Step1: Calculate the concentration of pink particles in Solution A
Concentration = (\frac{\text{Number of pink particles}}{\text{Volume of solvent}}). In Solution A, there are 9 pink particles and solvent volume is (40\space mL). So concentration (C_A=\frac{9}{40}= 0.225\space\text{particles/mL})
Step2: Calculate the concentration of pink particles in Solution B
In Solution B, there are 2 pink particles and solvent volume is (45\space mL). So concentration (C_B=\frac{2}{45}\approx0.044\space\text{particles/mL})
Answer:
Solution A
