Question

A gas has an initial volume of 21.7 L at a pressure of 0.4 atm and a temperature of 252 K. The pressure of the gas increases to 2 atm as the temperature increases to 323 K. What is the final volume of the gas? 3.4 L 5.6 L 8.5 L 11.1 L

Answer 1

the final volume of the gas is 5.56 L

Step-by-step explanation:

The computation of the final volume of the gas is as follows:

Here we presume that gas is an ideal gas

So we use the following equation

PV = nRT

P1V1 ÷ T1 = P2V2 ÷ T2

V2 = P1V1T2 ÷ T1P2

V2 = 0.4(21.7)(323) ÷ 252 (2)

V2 = 5.56 L

Hence, the final volume of the gas is 5.56 L
