Calculate the change in mass of an object if 800 electrons are given to it Given: Mass of an electron is `9.1xx10^(-31)` kg .

Explanation

To calculate the change in mass of an object when 800 electrons are added to it, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the mass of a single electron**:
The mass of one electron is given as \( 9.1 \times 10^{-31} \) kg.

2. **Calculate the total mass of 800 electrons**:
