Using the given values and the ideal gas law, there are approximately 0.404 moles of O2.
How to find the number of moles of O2 using the ideal gas law
To find the number of moles of O2 using the ideal gas law, know the volume (V), temperature (T), pressure (P), and the ideal gas constant (R).
Given values:
Volume (V) = 10 liters
Temperature (T) = 298 Kelvin
Pressure (P) = 1 atmosphere (which is approximately 101.325 kilopascals)
Ideal gas constant (R) = 0.0821 liter·atm/(mol·K)
Using the ideal gas law equation:
PV = nRT
We can rearrange it to solve for the number of moles (n):
n = PV / RT
Plug in the values:
n = (1 atm) * (10 L) / (0.0821 L·atm/(mol·K) * 298 K)
Calculating this expression:
n ≈ 0.404 moles of O2
Therefore, using the given values and the ideal gas law, there are approximately 0.404 moles of O2.
Complete question
Ideal gas law. First find mol of O2 Then use V=nRT/P. Given that volume = 10 liters, temperature = 298 kelvin and pressure = 1 atm
