Some Trivia – the average volume of the driver side air bag in a regular car is ~56L while the passenger side air bag is 120L. Obviously these numbers vary a little base on the model and year of the car. Question: If we were to use the reaction between Zn and HCl to fully inflate the driver side air bag (to 1 Atm) at 25oC, how many grams of Zn would be required. (Assume you have sufficient HCl to...
