Question

Part A How many electrons does each sphere contain?(The atomic mass of aluminum is 26.982 grams per mole, and itsatomic number is 13.)

Part B Part C What fraction of all the electrons in one ofthe spheres does this represent? Two small aluminum spheres, each of mass 0.0250 kilograms, areseparated 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 itsatomic number is 13.) Part B How many electrons would have to be removedfrom one sphere and added to the other to cause an attractive forcebetween the spheres of magnitude 1.00 x 10^4 (roughly one ton)? Assume that the spheres may be treated as pointcharges. Part C What fraction of all the electrons in one ofthe spheres does this represent?

Explanation / Answer

Part A: 7.25×1024 Part B: 5.27×1015 Part C: 7.26×1010
