If the two flasks are connected through a stopcock and the stopcock is opened, what is the partial pressure of helium? torr Submit My Answers Give Up Incorrect, Try Again; 3 attempts remaining Incorrect; Try Again; 3 attempts remaining Part B If the two flasks are connected through a stopcock and the stopcock is opened pressure of argon? what is the partial A.cp Ar = torr Submit My Answers Give Up art C If the two flasks are connected through a stopcock and the stopcock is opened, what is the total pressure?

Explanation / Answer

part A

P1V1 = P2V2

757*270 = (475+270)*p2

partial pressures of He = P2 = 274.35 torr

part B

P1V1 = P2V2

721*475 = (475+270)*p2

partial pressures of Ar = P2 = 459.7 torr
