Answer:  0.02 moles

Explanation: Using ideal gas equation:  

PV=nRT

n=\frac{PV}{RT}

P = pressure = standard pressure= 1 atm

V = volume = 0.500L

n = no of moles = ?

R = gas constant =0.0821 Latm\molK

T= temperature = 15^0C = (15+273)K= 288K

n=\frac{1\times 0.500}{0.0821\times 288}=0.02moles
