Ideal Gas Law
The relationship between the volume, pressure, temperature, and moles of a gas is described by the Ideal Gas Law:
PV = nRT
Where:
* P is the pressure in atmospheres (atm)
* V is the volume in liters (L)
* n is the number of moles
* R is the ideal gas constant (0.0821 L·atm/mol·K)
* T is the temperature in Kelvin (K)
To find the volume, you need to know the following:
1. Number of moles (n): You provided this, 0.25 moles.
2. Temperature (T): You need to know the temperature in Kelvin.
3. Pressure (P): You need to know the pressure in atmospheres.
Example
Let's say the temperature is 25°C (298 K) and the pressure is 1 atm. Then, you can calculate the volume:
V = (nRT) / P
V = (0.25 mol * 0.0821 L·atm/mol·K * 298 K) / 1 atm
V ≈ 6.14 L
Conclusion
Without knowing the temperature and pressure, you can't calculate the volume of 0.25 moles of oxygen.
