Calculate the final pressure using Boyle's Law:
P1 = 753 torr
V1 = 280 mL
V2 = 280 mL + 480 mL = 760 mL
A 280-mL flask contains pure helium at a pressure of 753 torr . A second flask with a volume of 480 mL contains pure argon at a pressure of 723 torr .
If we connect the two flasks through a stopcock and we open the stopcock, what is the partial pressure of helium?
