Got it from getting it wrong
Answer: 25.5 degrees celsius
Explanation:
Use the combined gas law.
P1V1 / T1=P2V2 / T2
Let the subscript 1 represent the initial 18.0L of gas and the subscript 2 represent the gas at the final volume of 27.0L.
T1=430.0K, P1=2.40atm, V1=18.0L, P2=1.10atm, V2=27.0L, and T2 is unknown.
Substitute the known values into the combined gas law equation.
P1V1 / T1=P2V2 / T2→(2.40atm)(18.0L) / (430.0K)=(1.10atm)(27.0L) / T2
Solve the equation for T2, simplify, and report the answer with three significant figures.
T2=P2V2T1 / P1V1= (1.10atm)(27.0L)(430.0K) / (2.40atm)(18.0L)=295.625K
To get the temperature in Celsius, subtract 273.15.
T2=22.5∘C
