Chemistry

The charge on an electron is a fundamental constant in physics, which is -1.602 x 10^-19 coulombs. It is important to note that the charge on an electron is always the same, regardless of the quantity of electrons present.

To determine the charge on a specific number of electrons, such as 500 milligrams (mg) of electrons, we need to convert the mass into the number of electrons.

First, we need to determine the number of moles of electrons. We can do this by using the molar mass of electrons, which is approximately 9.109 x 10^-31 kilograms per electron.

Step 1: Convert 500 milligrams (mg) to kilograms (kg):
500 mg * (1 gram / 1000 mg) * (1 kilogram / 1000 grams) = 0.0005 kilograms

Step 2: Calculate the number of moles of electrons:
Number of moles = Mass / molar mass
Number of moles = 0.0005 kg / (9.109 x 10^-31 kg/electron) ≈ 5.489 x 10^25 moles

Step 3: Calculate the total charge:
Total charge = number of moles * charge on one electron
Total charge = 5.489 x 10^25 moles * (-1.602 x 10^-19 C/mole) ≈ -8.8 x 10^6 coulombs

Therefore, 500 mg of electrons would have a charge of approximately -8.8 x 10^6 coulombs.
