what is the total charge in coulomb of 75kg of electron? Related: Ele...
Charge on one electron = 1.6 × 10⁻¹⁹ C,
i.e, 9.1 × 10⁻³¹ kg contains 1.6 × 10⁻¹⁹ C...
so, 75 kg contains (1.6 × 10⁻¹⁹ × 75)/(9.1 × 10⁻³¹) = 1.38 × 10¹³ electrons...

Answer:


Electric Charges Introduction


Electric charges are the fundamental property of matter. There are two types of electric charges: positive and negative. Like charges repel each other, and unlike charges attract each other. The unit of electric charge is coulomb (C).

Charge of an electron


The charge of an electron is negative and is equal to -1.602 x 10^-19 C.

Total charge in coulombs of 75kg of electron


To find the total charge in coulombs of 75kg of electrons, we need to know the number of electrons in 75kg of matter.

The mass of one electron is 9.11 x 10^-31 kg.

Therefore, the number of electrons in 75kg of matter can be calculated as:

Number of electrons = (75 kg) / (9.11 x 10^-31 kg/electron)

Number of electrons = 8.23 x 10^33 electrons

The total charge in coulombs of 75kg of electrons can be calculated as:

Total charge = (Number of electrons) x (Charge of one electron)

Total charge = (8.23 x 10^33 electrons) x (-1.602 x 10^-19 C/electron)

Total charge = -1.32 x 10^15 C

Therefore, the total charge in coulombs of 75kg of electrons is -1.32 x 10^15 C.
