Answer:
47.01g/mol
Explanation:
The formula of Nitrous acid is HNO₂:
The formula mass of a compound gives the sum of the atomic masses of the elements that makes up a compound.
Atomic mass of H = 1.0079g/mol
N = 14.0067g/mol
O = 15.9994g/mol
Formula mass of HNO₂ = 1.0079 + 14.0067 + 2(15.9994)
= 1.0079 + 14.0067 +31.9988
= 47.01g/mol
There are 2 Nitrogen atoms (or parts) of Nitrogen on the left side of the equation, and 2 Hydrogen, and only one Nitrogen but three Hydrogen on the other side. Where did the extra Nitrogen go? Where did that Hydrogen come from? The answer is Stoichiometry.
N2 + H2 --> NH3 has to be balanced, so we add coefficients to the reactants and products, which indicate in what ratio they are consumed in the reaction. They effectively multiply the subscripts on the elements.
To balance Nitrogen, we have to add a 2 to the front of NH3, so we get 2NH3. Nitrogen is balanced, but Hydrogen isn't. There are now 6 Hydrogen being produced by the reaction, so we can add a 3 to the products side, making 3H2.
Now we have N2 + 3H2 --> 2NH3, and everything is balanced.
The ratio is 2:6, or 1:3
Polyatomic ion: a covalently bonded group of atoms that has a positive or negative charge and acts as a unit.

Answer:
It releases nutrients which causes rapid growth of planktons which leads to oxygen deficiency leading to death of aquatic animals,a phenomenon known as eutrophication.
