Agas is heated from 298 k to 367 k while its volume changes from 2.5 l to 3.9 l. if the initial pressure of the gas is 1.1 atm, what is the final pressure of the gas? 0.57 atm 0.87 atm 1.4 atm 2.1 atm

The final pressure of the gas is 0.87 atm

Explanation:

Step 1: What formula

To find the final pressure, we will use following equation:

P*V / T

Step 2: Data given:

Temperature T1 = 298K

Temperature T2 = 367K

Volume V1 = 2.5L

Volume V2 = 3.9L

Pressure p1 = 1.1 atm

Pressure p2 = TO BE DETERMINED

Step 3: equation in this case

(p1 * V1)/ T1   = (p2 * V2) / T2

(1.1 *2.5) / 298  = (3.9 * p2 ) / 367

0.009228 = 3.9 * p2

p2 = 0.868378 atm ≈ 0.87 atm

The final pressure of the gas is 0.87 atm

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