Question

A 285-mL flask contains pure helium at a pressure of 750 torr . A second flask with a volume of 455 mL contains pure argon at a pressure of 732 torr .If we connect the two flasks through a stopcock and we open the stopcock, what is the partial pressure of helium

Explanation:

Given data

Required

Partial pressure of helium

Solution

First calculate the total volume of gas mixture once the stopcock is opened

So

As temperature remains constant,by Boyle’s Law we calculate the partial pressure of the helium gas

So

2. Explanation:

Below is an attachment containing the solution.
