Answer:
The number of moles present is 68267.08 moles
Step-by-step explanation:
V = 4.0L
P = 560kPa = 560*10³Pa
T = 127°C = (127 + 273.15)K = 400.15K
Number of moles (n) = ?
R = 0.082J / mol.K
From ideal gas equation,
PV = nRT
n = PV / RT
n = (560*10³ * 4.0) / (0.082 * 400.15)
n = 2240000 / 32.8123
n = 68267.08 moles
The number of moles present is 68267.08 moles
