Having a Gas with Cola

In this activity, learners measure the amount of carbon dioxide in a carbonated drink. Learners work in teams of at least two to extract, collect, and measure gas (volume) from a can or bottle of cola. Learners can also compare the volume of gas to the mass loss and determine the molarity of the CO2 in the cola.
