To find the volume of the gas at STP (Standard Temperature and Pressure), we need to use the ideal gas law equation:
PV = nRT
Where:
P = pressure
V = volume
n = number of moles
R = ideal gas constant
T = temperature
At 25 degrees Celsius, the temperature is 298 K (25 + 273). The pressure is 2 atm.
Now, we can rearrange the equation to solve for the volume at STP:
V1/T1 = V2/T2
(2 atm)(500 mL) / 298 K = (1 atm)(V2) / 273 K
V2 = (2 atm)(500 mL)(273 K) / (1 atm)(298 K)
V2 = 364.43 mL
Therefore, the gas would occupy 364.43 mL at STP.
