A sample of neon gas at 1.20 atm compresses from 0.250 L to 0.125 L. If the temperature remains constant, what is the final pressure?

P1V1 = P2V2

2.4

To find the final pressure, you can use the relationship between pressure and volume known as Boyle's Law. It states that when the temperature of a gas remains constant, the product of pressure and volume is constant.

Boyle's Law formula: P1V1 = P2V2

Where:
P1 = initial pressure
V1 = initial volume
P2 = final pressure (what we need to find)
V2 = final volume

Given values:
P1 = 1.20 atm (initial pressure)
V1 = 0.250 L (initial volume)
V2 = 0.125 L (final volume)

Now, rearrange the formula to solve for P2:
P2 = (P1 * V1) / V2

Substituting the given values:
P2 = (1.20 atm * 0.250 L) / 0.125 L

P2 = 3.0 atm

Therefore, the final pressure is 3.0 atm.
