Question

A 295-mL flask contains pure helium at a pressure of 747 torr . A second flask with a volume of 480 mL contains pure argon at a pressure of 717 torr.

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

PHe = ??? torr

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

PAr = ??? torr

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

Ptotal =?? torr
