To calculate the charge on 500 mg of electrons, we first convert the mass to grams: 500 mg = 0.5 g. The number of moles of electrons can be found using the molar mass of electrons, which is approximately 0.00054858 g/mol. Therefore, 0.5 g corresponds to about 910 moles of electrons. Since each electron has a charge of approximately -1.602 x 10^-19 coulombs, the total charge is about -1.46 x 10^21 coulombs.

How many electrons does it take to make 80qC (microcoulombs) of charge?
To calculate the number of electrons in 80 μC of charge, you can use the formula (Q = Ne), where (Q) is the charge in coulombs, (N) is the number of electrons, and (e) is the elementary charge ((1.6 \times 10^{-19}) Coulombs). First, convert 80 μC to coulombs (1 μC = (10^{-6}) C), then divide the charge by the elementary charge to find the number of electrons.
