Answer:
n = 0.39 mol
Explanation:
Given data:
Number of moles = ?
Volume = 5 L (5/1000 = 0.005 m³)
Pressure = 225 Kpa (225×1000 = 225000 Nm⁻²)
Temperature = 75°C (75+273.15 = 348.15 K)
R = 8.314 Nm K⁻¹ mol⁻¹
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant
T = temperature in kelvin
n = PV/RT
n = 225000 Nm⁻² ×0.005 m³/ 8.314 Nm K⁻¹ mol⁻¹ ×348.15 K
n = 1125 /2894.52 / mol
n = 0.39 mol
