Question

A gas has an initial volume of 2.5 L at a temperature of 275 K and a pressure of 2.1 atm. The pressure of the gas increases to 2.7 atm, and the temperature of the gas increases to 298 K.

The final volume of the gas, rounded to the nearest tenth, is.

Answer 1

The following information are given:
V1 = 2.5L
T1 = 275K
P1 = 2.1 atm
T2 = 298K
P2 = 2.7 atm
V2 = ?
The formular for solving the equation is: P1V1T1 = P2V2T2
V2 = P1V1T1/P2VT2
V2 = 2.5 * 275 * 2.7 * 298 = 1443.75/804.6 = 1.794
Therefore, V2 = 1.8L.

Answer 2

Its 2.1, I just took the test, the verified answer is wrong.
