Hi, can someone help me with this problem. Thanks!
A 280 ml flask contains pure helium at a pressure of 717 torr. A second flask contains pure argon at a pressure of 732 torr. If the two flasks are connected through a stopcock and the stopcock is opened, what is the partial pressure of helium?
Well, the formula of partial pressure is P = n RT/V but in this case both T and n is not given. So how can I solve this problem.
