Asked by Rose
A 260-ml flask contains pure helium at a pressure of 756torr . A second flask with a volume of 470ml 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?
B)If the two flasks are connected through a stopcock and the stopcock is opened, what is the partial pressure of argon?
C)If the two flasks are connected through a stopcock and the stopcock is opened, what is the total pressure?

PV = nRT. Calculate n for each flask.
a. moles He and PV = nRT calculates He partial pressure using total volume for V.
b. moles Ar and PV = nRT calculates Ar partial pressure using total volume for V.
c. total pressure is sum of partial pressures.
