What is the total charge on 75.0 kg of electrons ?

Explanation

To find the total charge on 75.0 kg of electrons, we can follow these steps:

### Step 1: Determine the mass of one electron
The mass of one electron is given as:
\[ m_e = 9.1 \times 10^{-31} \text{ kg} \]

### Step 2: Calculate the number of electrons in 75 kg
To find the number of electrons in 75 kg, we divide the total mass by the mass of one electron:
