Assignment:
Take a deep breath of air and assume it is one liter of air. What is the probability that the liter of air contains a molecule from Julius Caesar's last breath (also assume a liter of air)? Assume that the nitrogen that existed in the atmosphere ~ 2000 years ago is that which is currently present and that the liter of air has had a chance to randomly distribute in the atmosphere in the last 2000 years. Show calculations.
Provide complete and step by step solution for the question and show calculations and use formulas.
