1. a sample of argon at a pressure of 785 mm hg is transferred from a 125 ml dask to a 15 ml
assuming constant temperature, what is the pressure inside the 155 ml flask?

The pressure of argon inside the 155 ml flask is approximately 633 mm Hg.

Explanation:

Given:

The temperature is constant. So, the process is isothermal.

Initial pressure of argon is,

Initial volume of argon is,

Final volume of argon is,

Final pressure of argon is,

Now, as per Boyle's law, for an isothermal process, the product of pressure and volume is always a constant or . Therefore, we can write it as:

Rewriting the above in terms of , we have:

Plug in 785 for , 125 for , 155 for and solve for . This gives,

Therefore, the pressure of argon inside the 155 ml flask is approximately 633 mm Hg.
