Question

1. compare the four solutions in the diagram in terms of the amount of solute and the volume of the solutions. solution _ is the most concentrated solution. solution _ is the most diluted solution. solution b has the same concentration as solution ____.

Explanation:

Step1: Count solute particles

A has 5, B has 10, C has 5, D has 10.

Step2: Consider solution volume

A and B are 100 mL, C and D are 50 mL.

Step3: Calculate concentration

Concentration = $\frac{\text{Solute amount}}{\text{Solution volume}}$. D has highest, A has lowest. B and D have same ratio.

Answer:

D; A; D
