2. calculate the molarity of 500.0 grams of li2s in a total volume of 4.44 liters?
[li2s molar mass = 46.0 grams/mol

2.448 M ≅ 2.45 M.

Explanation:

Molarity (M) is the no. of moles of solute that dissolved in 1.0 L of the solution.

M = (no. of moles of solute)/(V of the solution (L).

M = (mass/molar mass) Li₂S / (V of the solution (L))

∴ M of Li₂S = (500.0 g/46.4 g/mol)/(4.44 L) = 2.448 M ≅ 2.45 M.

- "the acute form of diverticulitis can manifest itself with one or more severe attacks of infection and inflammation.

the inflammation of diverticulitis can eventually result in a bowel obstruction, which may cause constipation, thin stools, diarrhea, abdominal swelling or bloating, and abdominal pain."

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
