Answer:
1 mole
Explanation:
At Standard Temperature and Pressure (273.15 Kelvin and 1 atmosphere), 22.4 L of gas is always equal to 1 mole.
We can use the Ideal Gas Equation to explain this: [tex]PV=nRT[/tex]
At STP, like noted above, the Pressure is 1 atmosphere (or 101,325 Pa) and 273.15 Kelvin. Using this information, we can determine that the Ideal Gas Constant, R, is 0.08206. We can now solve this equation.
[tex](1 atm)(22.4 L)=n(0.08206)(273.15)\\\\22.4 = n(22.4)\\\\\frac{22.4}{22.4} = \frac{n(22.4)}{22.4}\\ \\ n = 1[/tex]
