PLEASE HELP ME

Hello!

The ball took up 2,9L

To solve this problem, we should apply the ideal gas law and clear for n (the number of moles), as this value doesn't change when Devin takes the ball to the garage:

$n= \frac{P1*V1}{RT1}=\frac{P2*V2}{RT2}$

Now, we should clear this equation to find V2, as this is the value we are looking for:

$V2= \frac{P1*V1*T2}{P2*T1}= \frac{400kPa*3L*250K}{350kPa*300K}=2,857L$ ≈2,9L

Have a nice day!
