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. How many molecules are in 1 mole of molecules. Next: Question 8: Conversion of mass into the mole. 1 mole N2 and 3 moles H2, some amount x of N2 will react with 3x amount of H2 to form 2x amount of ammonia, due to stoichiometric coefficients.

In the first case, a tampon with liquid nitrogen is used, in the second case the same substance is injected with a … Your email address will not be published. To convert from moles to atoms, multiply the molar amount by Avogadro's number. Mass of 1 atom of nitrogen = 14g/(6.022 × 10 23 atoms) Mass of 1 atom of nitrogen = 2.325 × 10-23. to get the answer, we have 28g = 2.02 x10^23 molecules. Asked By: Branislav Errani | Last Updated: 5th February, 2020, Avogadro's number is a very important relationship to remember: 1, So, in one mole of nitrogen gas you have 6.022⋅, In order to work this out, multiply Avogadro's number - the one I stated at the start of this explanation - by 2 . The number of carbon atoms in exactly 12 g is called Avogadro's number , .One mole is the amount of material which contains Avogradro's number of particle. but we want 1g = how many molecules. So, in one moleof nitrogen gas you have 6.022⋅1023 molecules of nitrogen gas, N2. (a) Mass of nitrogen atom = number of moles x atomic mass.
