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
Answer:
answer is 0.225 atm
Explanation:
