A 280-mL flask contains pure helium at a pressure of 748 torr. A second flask with a volume of 460 mL contains pure argon at a pressure of 719 torr.If we connect the two flasks through a stopcock and we open the stopcock, what is the partial pressure of helium? Express the partial pressure in torr to three significant figures.
