A 5.15 L ballon has a pressure of 1.35 atm. If compressed to 3.43L , what will be the resulting pressure ?

The resulting pressure will be 2.03 atm.

Explanation:

As per the Boyle's law, the volume of a particular mass of a gas is inversely proportional to its pressure applied. As pressure increases, the volume decreases.

P1V1 = P2V2

Here P1 = 1.35 atm

V1 = 5.15 L

P2 = ?

V2 = 3.43 L

The above equation can be rewritten to get P2 as,

P2 =

Now, we can plugin the above values as,

P2 =

   = 2.03 atm

As per the law said, the volume is compressed as the pressure increases.

the atomic mass is the bottom number on the element.
