The GMM of NH₃ is 17 gExplanation:The Gram Molecular Mass is mass in GRAMS of one mole of a molecular substance in grams.Given here: -The ELEMENTS are N and H. Here, H has 1 gm RAM and N has 14 gm RAM Now NH₃ has 1 atom of N and 3 atoms of H. So, the GMM is calculated by - 14X1 + 1X3 = 14+3=17gHence, the GMM of NH₃ or Ammonia is 17g

The AVOGADRO number of MOLECULES and atoms gives the number of entities in a mole, which is approximately 6.023 × 1023 entities per mol. For CO2 MOLECULE, the ENTITY is a molecule MADE up of 3 atoms. 1 mole of CO2 contains only 1 carbon atom. Therefore, there are 6.023 x 1023 atoms of carbon.
