It is possible that it was the site of the early medieval nunnery founded in the late 7th century by Saint Werburh, dedicated to Saint Ãthelthryth, Ã¦thelthryth and probably destroyed by The danes. c. 870

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.
