A second flask with a volume of 495 mL contains pure argon at a pressure of 726 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. If we connect the two flasks through a stopcock and we open the stopcock, what is the partial pressure of argon? Express the partial pressure in torr to three significant figures. If we connect the two flasks through a stopcock and we open the stopcock, what is the total pressure? Express the total pressure in torr to three significant figures
