question_answer 62)

  Which has more number of atoms? 100 g of N3 or 100 g of

Answer:

  Molar mass of                 N2 = 2 x 14 = 28 g 28 g of  has number of molecules = 6.022 x 1023 100 g of has number or molecules Atoms in 100 g of                    atoms Similarly, molar mass of 17 g  has number of molecules = 6.022 x 1023 100 g of  has number of molecules Atoms in 100 g of Thus, 100 g of  has more number of atoms.
