Question

A sample of krypton occupies 15.0 L at a pressure of 2.1 atm. Use Boyle's Law to find the pressure of the krypton when the volume is decreased to 4L.

Answer 1

7.5 atm

Step-by-step explanation:

Given that,

Initial volume, V₁ = 15 L

Pressure, P₁ = 2.1 atm

Final volume, V₂ = 4L

We need to find the final pressure. The mathematical relation between volume and pressure is given by :

`(V_1)/(V_2)=(P_2)/(P_1)\\\\P_2=(V_1P_1)/(V_2)\\\\P_2=(15* 2)/(4)\\\\P_2=7.5\ atm`

So, the final pressure is equal to 7.5 atm.
