Carbon dioxide gas occupies a volume of 20.0 L at 308K and 2.30 atm. What volume would it occupy at 416 K and 5.40 atm?

The new volume is 11.5 L

Explanation:

Step 1: Data given

Volume of carbon dioxide gas = 20.0 L

Initial temperature = 308 K

Initial pressure = 2.30 atm

The temperature changes to 416 K

The pressure changes to 5.40 atm

Step 2: Calculate the new volume

(P1*V1)/T1 = (P2*V2)/T2

⇒ with P1 = the initial pressure = 2.30 atm

⇒ with V1 = the initial volume = 20.0 L

⇒ with T1 = the initial temperature = 308 K

⇒ with P2 = the final pressure = 5.40 atm

⇒ with V2 = the final volume = TO BE DETERMINED

⇒ with T2 = the final temperature = 416 K

(2.30*20.0)/308 = (5.40*V2) / 416

V2 = 11.5 L

The new volume is 11.5 L

its first and third is your answer i did the qustion the fourth isnt right
