Challenge Problems
Push your limits with challenges.
Question 1
A reaction produces a gas that leads to a 5g mass loss over 10 minutes. What would be the average reaction rate in grams per minute?
💡 Hint: Think about how to relate total mass loss with the duration.
Question 2
If a container's initial mass is 120g and after some time it registers 110g while producing gas, calculate the mass of gas produced.
💡 Hint: Consider how mass conservation applies.
