Question

c)If the two flasks are connected through a stopcock and the stopcock is opened, what is the total pressure A 265-ml contains pure helium at a pressure of 750torr . A second flask with a volume of 485mL contains pure at a pressure of 718torr .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? If the two flasks are connected through a stopcock and the stopcock is opened, what is the total pressure?

Explanation / Answer

total volume : 485ml + 265ml = 750ml

750torr(265ml/750ml) = 265 torr for He

718torr(485ml/750ml) = 464.31 torr for Ar

265 + 464.31 = 729.31 torr total pressure
