Compare 1 mole of h2, 1 mole of o2 and 1 mole of f2
(a)which has the largest number of molecule? explain why
(b)which has the greatest mass? explain why

Explanation:

(a)  As per the mole concept, one mole of any atom contains atoms or molecules, that is, Avogadro's number of atoms.

Therefore, 1 mole of = molecules

                                           = molecules

   1 mole of = molecules

                                    = molecules

   1 mole of = molecules

                                    = molecules

Hence, there are equal number of molecules present in the given atoms.

(b)   Mass of each given atom will be calculated as follows.

                Mass = no. of moles × molar mass

As one molecule of contains 2 atoms of hydrogen.

So, mass of 1 mole of =

                                                     = 2.016 g

      mass of 1 mole of =

                                                     = 31.996 g

      mass of 1 mole of =

                                                     = 37.996 g

Thus, we can conclude that has the greatest mass.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
