What is the moles of 4.48 L of CO2 at STP?

From the molar gas volume 1 mole of a gas at standard temperature and pressure occupies a volume of 2.24 liters. Therefore; 1 mole of CO2 = 2.24 liters; thus; 4.48 L will have; 4.48/2.24 = 2 moles Hence, 2 moles of CO2 at STP will occupy a volume of 4.48 L
