Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
Calculate the mass by volume percentage for 8g of solute in 120mL of solution.
๐ก Hint: Use the formula: (mass of solute/volume of solution) x 100.
Question 2
Easy
If you have a solution of 5g of salt in 50mL of water, what is the mass by volume percentage?
๐ก Hint: Remember, percentage means you need to multiply by 100.

Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula for calculating mass by volume percentage?
- (mass of solute/volume of solution) x 100
- (volume of solute/total mass) x 100
- (mass of solution/volume of solute) x 100
๐ก Hint: Remember it involves the mass of solute over the volume of the solution.
Question 2
True or False: The mass by volume percentage is always less than 100%.
- True
- False
๐ก Hint: Think about what a percentage represents.

Challenge Problems
Push your limits with challenges.
Question 1
You have a solution prepared with 15g of solute in 300mL of water. If you evaporate 100mL of this solution, what will the new concentration be?
๐ก Hint: Focus on how evaporation affects both mass and volume.
Question 2
If a chemist needs a 12% mass by volume solution and has 1000mL of solution, how much solute is required?
๐ก Hint: Use the mass by volume percentage formula in reverse.
