The volume of a gas is 450 mL when its pressure is 1.00 atm. If the temperature of the gas does not change, what is the pressure
Fudgin [204]

<u>Ans: 0.225 atm</u>

<u></u>

<u>Given:</u>

Initial volume of gas, V1 = 450 ml = 0.450 L

initial pressure, P1 = 1.00 atm

Final volume, V2 = 2.00 L

<u>To determine:</u>

Final pressure, P2

<u>Explanation:</u>

Based on ideal gas equation:

PV = nRT  ----(1)

where P = pressure, V = volume, n = # moles, R = gas constant, T = temp

Under constant, T and n, eq(1) can be expressed as:

PV = constant

(or) P1V1 = P2V2

P2 = P1V1/V2 = 1.00 atm * 0.450 L/2.00 L = 0.225 atm
