Calculate the number of nitrogen atoms in 240 g of ammonium nitrate?

Answer : The number of nitrogen atoms are,

Explanation : Given,

Mass of = 240 g

Molar mass of = 80 g/mole

First we have to calculate the moles of

As we know that contains 2 number of nitrogen atoms, 4 number of hydrogen atoms and 3 number of oxygen atoms.

Now we have to calculate the number of atoms of nitrogen.

As, 1 mole of contains number of nitrogen atoms

As, 3 mole of contains number of nitrogen atoms

Therefore, the number of nitrogen atoms are,

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
