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

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