To find the number of moles in 0.550 grams of LiCl, divide the mass by the molar mass of LiCl, which is approximately 42.4 g/mol. 0.550 g LiCl / 42.4 g/mol LiCl ≈ 0.013 mol LiCl. Therefore, the student has approximately 0.013 moles of LiCl.
You will have 8 valence electrons around Cl (it usually has 7 but gained one from Li). There are no valence electrons to show around Li because it gave it's valence electron to Cl. Answered by a chemistry teacher.

There would be three unshared pairs of electrons in a molecule of hydrogen iodide.
Germanium (Ge) has 2 lone pairs of electrons.
In carbon monoxide (CO), there are no unshared pairs of electrons. All the electrons are involved in bonding between carbon and oxygen.
The water molecule has two pairs of unbonded electrons, also known as lone pairs. These lone pairs are located on the oxygen atom.
