Ideal Gas Law Calculation
Understanding Ideal Gas Law Calculation
The Ideal Gas Law: PV = nRT
Where:
P = Pressure
V = Volume
n = Number of moles of gas
R = Gas constant (8.31 L-kPa/mol-K)
T = Temperature
Given data:
Volume (V) = 25.0 L
Pressure (P) = 101.5 kPa
Temperature (T) = 373 K
Calculating number of moles of gas (n) with the ideal gas law equation:
n = PV/RT
Substitute the values:
n = (101.5 kPa)(25.0 L) / (8.31 L-kPa/mol-K)(373 K)
n = 7.55 mol
The amount of gas we have is 7.55 mol, which is greater than the 4.89 mol needed for the reaction. Therefore, the statement "You will have enough gas" is accurate in this scenario.
