The pressure of a sample of helium in a 1.00-L container is 0.988 atm. What is the new pressure if the sample is placed in a 2.00-L container?

Answer : The new pressure if the sample placed in a 2.00-L container is, 0.494 atm.

Explanation :

Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

or,

where,

= initial pressure = 0.988 atm

= final pressure = ?

= initial volume = 1.00 L

= final volume = 2.00 L

Now put all the given values in the above equation, we get:

Thus, the new pressure if the sample placed in a 2.00-L container is, 0.494 atm.
