Aluminum Chloride has a formula of AlCl3 giving it 4 total atoms per molecule. Aluminum has a charge of +3 and Chlorine's most common charge is -1 meaning you need 3 chlorine for every 1 Aluminum to cancel the charges. Because of the chlorine, it would most likely be aqueous, or dissolved in a liquid. Aluminum Chloride has a formula of AlCl3 giving it 4 total atoms per molecule. Aluminum has a charge of +3 and Chlorine's most common charge is -1.
Two small aluminum spheres, each of mass 0.0250 kilograms, are separated by 80.0 centimeters. Part A How many electrons does each sphere contain? (The atomic mass of aluminum is 26.982 grams per mole, and its atomic number is 13.) Hint A.1 The definition of mole and atomic number In one mole ( ) of any material, there are approximately atoms present. The number of atoms per mole is called Avogadro's number . The atomic number of an element is the number of protons (and therefore also the number of electrons) in an atom of that element. Part A.2 How many electrons per mole of aluminum? How many electrons are there in a mole of aluminum? Express your answer numerically.
