If mass of an electron is `9.11xx10^(-31)`kg, how many electrons will weight 2 kg?

Explanation

To solve the problem of how many electrons weigh 2 kg, we can follow these steps:

### Step 1: Understand the given data
We know the mass of a single electron, which is given as:
\[ m = 9.11 \times 10^{-31} \text{ kg} \]
We need to find out how many electrons (let's denote this number as \( n \)) will weigh a total of 2 kg.

### Step 2: Set up the equation
