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,

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
