Answer:

n = 0.23moles

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
