Answer #1

Answer:-

_92.6__grams Hg atoms

_7.4__grams O atoms

1) mass of mercury atoms

      Given that 100−g sample of HgO contains 92.6 g mercury.

        Hg has 1 atom.

   Therefore, mass of Hg atoms = 1x 92.6 g = 92.6 g

2) mass of oxygen atoms

Given that 100−g sample of HgO contains 7.4 g oxygen.

Therefore, mass of oxygen atoms = 1x   7.4 g = 7.4 g
