Answer:
P₂ = 1.12 atm
Explanation:
To find the new pressure, you need to use the Combined Gas Law:

In this equation, "P₁", "V₁", and "T₁" represent the initial pressure, volume, and temperature. "P₂", "V₂", and "T₂" represent the new pressure, volume, and temperature. Before plugging the values into the equation, you need to 
(1) convert the pressure from mmHg to atm (760 mmHg = 1 atm)
(2) convert the temperatures from Celsius to Kelvin (°C + 273)
The final answer should have 3 sig figs like the given values.
P₁ = 365 mmHg / 760 = 0.480 atm            P₂ = ? atm
V₁ = 5.00 L                                                   V₂ = 2.30 L
T₁ = 20°C + 273 = 293 K                             T₂ = 40°C + 273 = 313 K
