A sample of neon gas at a pressure of 0.609 atm and a temperature of 25.0 °C, occupies a volume of 19.9 liters. If the gas is compressed at constant temperature to a

volume of 12.7 liters, the pressure of the gas sample will be
atm.​

Answer:

The pressure of the gas sample will be 0.954 atm.​

Step-by-step explanation:

Boyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant. That is, if the pressure increases, the volume decreases; conversely if the pressure decreases, the volume increases.

Boyle's law is expressed mathematically as:

Pressure * Volume = constant

o P * V = k

To determine the change in pressure or volume during a transformation at constant temperature, the following is true:

P1 · V1 = P2 · V2

That is, the product between the initial pressure and the initial volume is equal to the product of the final pressure times the final volume.

In this case:

  • P1= 0.609 atm
  • V1= 19.9 L
  • P2=?
  • V2= 12.7 L

Replacing:

0.609 atm* 19.9 L= P2* 12.7 L

Solving:


P2=(0.609 atm* 19.9 L)/(12.7 L)

P2= 0.954 atm

The pressure of the gas sample will be 0.954 atm.​
