Concentration and Dilution
Grade 10•45 minutes•VDOE CH.5 The student will investigate and understand that solutions behave in predictable and quantifiable ways. Key ideas
include
a) molar relationships determine solution concentration
Learning Objective
I can quantitatively analyze concentration and dilution problems using the molarity equation (M₁V₁ = M₂V₂).
Practice Questions
This lesson includes 7 practice questions to reinforce learning.
View questions preview
1. Define molarity and explain what it represents in the context of solutions.
2. If you have 5 grams of NaCl (molar mass = 58.44 g/mol) dissolved in 250 mL of water, what is the molarity of the solution?
3. Explain the process of dilution and why it changes the concentration of a solution.
