Explanation:
Electro negativity refers to the ability of an atom in a molecule to attract the shared pair of electrons of a bond closer to itself.
In a molecule, the polarity of bonds is determined by the relative electro negativity of the bonding atoms. If the difference in electro negativity between the atoms in a bond is significant, such a bond is polar in nature e.g H-Cl, H-Br, C-F, etc.
However, the occurrence of polar bonds in a molecule alone does not guarantee the polarity of the molecule. The polarity of a molecule also depends on the shape of the molecule since dipole moment is a vector quantity.
A molecule is polar when the resultant dipole moment which is determined by the shape of the molecule is non zero.
For instance, CO2 contains two polar C-O bonds but the molecule is non polar because the two dipole moments cancel out. Also, symmetrical molecules are nonpolar irrespective of the presence of polar bonds in the molecule.
So we know that the formula to calculate molarity is:
![M=\frac{moles}{L}](https://tex.z-dn.net/?f=%20M%3D%5Cfrac%7Bmoles%7D%7BL%7D%20%20)
Where M is the molarity, moles is the number of moles in the solution, and L is the volume of the solution in liters.
So we are given the molarity of the solution (5.80 M) and the volume of the solution in liters (6.5 L). So now we just need to plug these numbers in and solve for moles:
![5.80M=\frac{moles}{6.5L}](https://tex.z-dn.net/?f=%205.80M%3D%5Cfrac%7Bmoles%7D%7B6.5L%7D%20%20)
![moles=37.7](https://tex.z-dn.net/?f=%20moles%3D37.7%20)
So now we know that there are 37.7 moles of lithium nitrate in the solution.
Copper 2
Just like you how you would say Cu(I) as copper one, you would say Cu(II) as copper two. Nothing fancy.
