Answer 1

more I role of atomy - 6.022x102's atoms. A mole CGHIG there are o cunbon and 14 Hydrogen atom in euch lohiy moleenles, = 20 atory in euch Coltu i mole CG HIU = 20 mole atoms 3 moles N205 there are 2 pritrogen and 5 oxygen atom in each Nor molecules,

thereton 3 moles Noors = 3X17) moles atomy - 21 moly atoms, moles o siwen. it meurs there are 12 moles os atoms, d) 3 moles of water im H2o there are 2 Hydrogen atory and I oxyaen. atom in euch H2O In 3 mots of H2O there are total 3613) a gondly atome there for A = 20 mols atorry, B) - 21 rooles story c) 12 moles alors 12 - 9 mobs atom atomy mols highest number of money letion B heels of atoms It mieurs Noor is the answer
