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 when its volume is changed to 2.00 l? use mc004-1.jpg. 0.225 atm 0.444 atm 2.25 atm 4.44 atm

Ans: 0.225 atm

Given:

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

initial pressure, P1 = 1.00 atm

Final volume, V2 = 2.00 L

To determine:

Final pressure, P2

Explanation:

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

i think it is d. e because the next one is igneous.
