Question

The volume of a gas is 450 mL when its pressure is 1.00 atm. If the temperature of the gas does not change, what is the

pressure when its volume is changed to 2.00 L?
Use PV = P2V2.
0.225 atm
O 0.444 atm
O 2.25 atm
O 4.44 atm

Answer 1

Answer: 0.225 atm

Step-by-step explanation:

For this problem, we have to use Boyle's Law.

Boyle's Law: P₁V₁=P₂V₂

Since we are asked to find P₂, let's manipulate the equation.

P₂=(P₁V₁)/V₂

`P_(2) =((1.00atm)(0.45L))/(2.00L)`

With this equation, the liters cancel out and we will be left with atm.

P₂=0.225 atm
