Final answer:
The volume of air that contains 682ml of argon is referred to as the argon volume. To determine the total atmospheric volume containing this argon, additional information like argon concentration in the atmosphere is needed.
Step-by-step explanation:
The volume of air that contains 682ml of argon corresponds to the argon volume within a larger quantity of air. Argon is a component of the Earth's atmosphere, so in any given volume of atmospheric air, there is a percentage of argon present. To find the total volume of air containing 682ml of argon, we would need additional information regarding the concentration of argon in the atmosphere and possibly the conditions (temperature and pressure) if they differ from standard atmospheric conditions. If we assume standard conditions and a typical argon concentration of about 0.93% in the atmosphere, the total volume of air could be calculated by dividing the volume of argon by its percentage concentration in air. However, since the question does not provide specific concentration or conditions, one cannot accurately calculate the total atmospheric volume without more data.
