If we put one mole of gas into a 100 L container it will expand to the whole volme but that means that temperature and/or pressure have to change and then it is not STP any more! If we put 1 mole of gas into a 100 L container and we keep the temperatur at 0°C the pressure would go down to 0.224 bar. The total moles in the container $=2 mol$ Therefore the volume of the container $=44.8 L$ One mole of N consists of Avogadro's number of nitrogen atoms (and has a mass of 14.01 g), whereas 1 mole of N2 consists of Avogadro's number of molecules, each molecule having two nitrogen atoms. 50 grams Nitrogen to mol = 3.56972 mol.
