Moles of an ideal gas are : 0.288

In general, the gas equation can be written

$\large{\boxed{\bold{PV=nRT}}}$

where

P = pressure, atm

V = volume, liter

n = number of moles

R = gas constant = 0.082 l.atm / mol K

T = temperature, Kelvin

Volume=V=3 L

T = 45°C+273=318 K

P = 2.5 atm

$\tt n=(PV)/(RT)\\\\n=(2.5* 3)/(0.082* 318)\\\\n=0.288$
