How many moles of o are in 15.0 mol fe(no3)3?

Answer : The number of moles of oxygen atoms are 135 moles.

Explanation : Given,

Moles of = 15.0 mole

The given chemical formula is,

By the mole concept:

In , there are 1 mole of iron (Fe) atom, 3 moles of nitrogen (N) atoms and 9 moles of oxygen (O) atoms.

As, 1 mole of contains 9 moles of oxygen atoms

So, 15.0 moles of contains moles of oxygen atoms.

Hence, the number of moles of oxygen atoms are 135 moles.

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table
