Answer:
3 electrons is contributed from each Nitrogen atom.
Total 6 electrons are shared in N₂.
Explanation:
- Nitrogen is belong to group VA
- it have 5 electron in its outer most Shell.
- it need 3 electrons complete its octet to become stable.
- Nitrogen have total 7 electrons.
- its atomic number is 7
The electronic configuration of Nitrogen is as:
1s², 2s², 2p³
it exist in diatomic form standard temperature and pressure.
Nitrogen form covalent bond and share 3 electron from each side.
total 6 electron are shared between 2 nitrogen atom.
For Covalent bonding it can share its 3 electrons.

The mass of salt dissolved in 1.0 L of 0.010 M SO₄²⁻ is 0.67 g/l
<h3>How can we Calculate the mass of the salt dissolve in 1.0 L of 0.010 M SO₄²⁻ ?</h3>To calculate the mass of the salt dissolved, we multiply by the mass of 1 mole to molar solubilty and lets assume we are using the anhydrous salt CaSO₄ for which the Molar Mass (M) = 136.1
Mass of the salt dissolved = Molar solubility x Molar mass
Molar Mass (M) = 136.1
Molar solubility = ?
Formula to find molar solubilty ;
Molar solubility = Square root of Solubity product (Given)
S = (Value of Solubity product is given in the question)
= 4.9 × 10⁻³
Mass of the salt dissolved = Molar solubility x Molar mass
= 4.9 × 10⁻³ x 136.1
= 0.67 g/l
