Final answer:
To determine the coulombs of charge that moved through a calculator with 1.80×1020 electrons, you multiply the number of electrons by the charge of a single electron, resulting in a total charge of approximately 28.836 coulombs.
Step-by-step explanation:
To calculate how many coulombs of charge moved through a pocket calculator when 1.80×1020 electrons move through it, we need to use the charge of a single electron. The charge of one electron is approximately -1.602×10-19 coulombs. Therefore, to find the total charge, we multiply the number of electrons by the charge of one electron.
For 1.80×1020 electrons, the calculation is as follows:
- Total Charge (C) = Number of electrons × Charge of one electron
- Total Charge (C) = 1.80×1020 × (-1.602×10-19)
- Total Charge (C) = -28.836 coulombs
Note that the charge comes out to be negative because electrons carry negative charge. However, when referring to the magnitude of charge that has moved, we can simply state the absolute value: 28.836 coulombs.
