Answer:
The final pressure of the gas sample at constant temperature is 1.20 atm.
Explanation:
Boyle's Law : Volume occupied by fixed amount of gas at a given temperature is inversely proportional to pressure .(moles, temperature are constant )
on transposing ,
PV = constant
............(1)
Initial pressure = P1 = 2.00 atm
Final pressure = P2 = ?
Initial volume = V1 = 300.0 mL
Final volume = V2 = 500.0 mL
Putting values of P1 ,V1, V2 in equation (1) and solving for P2
P2 = 1.20 atm at constant temperature
