$\boxed{{\text{3}}\;{\text{covalent bonds}}}$ are formed by nitrogen if each of its unpaired electrons participates in one bond.

Further Explanation:

The bond that is formed by the mutual sharing of electrons between the bonded atoms is called a covalent bond. It is also known as a molecular bond. Covalent compounds are those compounds which are formed by the electron sharing between two or more non-metals.

The octet rule is the rule in accordance to which the elements have the tendency to bond with other elements and acquire eight electrons in their valence shells. This results in achieving a stable noble gas configuration.

For example, the formation of NaCl occurs according to the octet rule. The electronic configuration of sodium is ${\text{1}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{p}}^{\text{6}}}{\text{3}}{{\text{s}}^{\text{1}}}$ while that of chlorine is ${\text{1}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{p}}^{\text{6}}}{\text{3}}{{\text{s}}^{\text{2}}}{\text{3}}{{\text{p}}^{\text{5}}}$ .

Chlorine is one electron short of the stable noble gas configuration and sodium can achieve stable configuration by losing an electron. So sodium loses an electron and forms cation and chlorine gains that electron to complete its octet.

The atomic number of nitrogen is 7. Its ground state electronic configuration is ${\mathbf{1}}{{\mathbf{s}}^{\mathbf{2}}}{\mathbf{2}}{{\mathbf{s}}^{\mathbf{2}}}{\mathbf{2}}{{\mathbf{p}}^{\mathbf{3}}}$ . The partial orbital diagram is the diagrammatic representation of the distribution of electrons in the valence shell only. In case of nitrogen, the valence shell is 2.

Nitrogen has five electrons in its valence shell. Out of these five electrons, two are paired while three remain unpaired. If all three unpaired electrons are to be used, it will accept three electrons from the neighboring atoms to make three covalent bonds.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
