Answer:
n = 0.23moles
Step-by-step explanation:
Number of moles = ?
Pressure at STP = 1atm
Volume = 5.24L
Temperature at STP = 273.15K
From ideal gas equation,
PV = nRT
P = pressure of the ideal gas
V = volume of the ideal gas
n = number of moles present
R = ideal gas constant = 0.082J/mol.K
T = temperature of the gas in Kelvin(K)
PV = nRT
n = PV / RT
n = (1 * 5.24) / (0.082 * 273.15)
n = 5.24 / 22.3983
n = 0.23 moles
The number of moles present is 0.23 moles
