A 285-mL flask contains pure helium at a pressure of 753 torr . A second flask with a volume of 470 mL contains pure argon at a pressure of 721 torr .

Part A If the two flasks are connected through a stopcock and the stopcock is opened, what is the partial pressure of helium?

Part B If the two flasks are connected through a stopcock and the stopcock is opened, what is the partial pressure of argon?

Part C If the two flasks are connected through a stopcock and the stopcock is opened, what is the total pressure?
