Does Air Have a Mass?

Hello! Happy Wednesday!

Today in Science we set out to prove that air has a mass.

Using a 2L pop bottle, a bottle pump and an electronic scale, we pumped air into our bottle in 25-pump increments and noted the mass each time. We noticed that while the changes weren't huge, we did see the mass of the bottle begin to increase in increments of 0,1g thus proving that yes, air does have a mass!

Please ask me about the experiment: What did I notice? What was the biggest challenge? What calculations were necessary? What is the mass of one single pump of air?
