Answer:
The pressure of the gas would be 3.06 atm
Step-by-step explanation:
Amonton's law states that the pressure is directly proportional to the absolute temperature of a gas under constant volume. The equation is:
P1 / T1 = P2 / T2
Where P1 is the initial pressure = 3.16atm
T1 is initial absolute temperature = 273.15 + 32.2°C = 305.35K
P2 is our incognite
And T2 is = 273.15 + 22.9°C = 296.05K
Replacing:
3.16atm / 305.35K = P2 / 296.05K
3.06 atm = P2
The pressure of the gas would be 3.06 atm
