How many protons weight 5kg? The mass of a proton is `1.67xx10^(-27)kg`.

Explanation

To find out how many protons weigh 5 kg, we can follow these steps:

### Step 1: Understand the given information
We know the mass of a single proton is \(1.67 \times 10^{-27} \, \text{kg}\) and we want to find out how many protons make up a total mass of 5 kg.

### Step 2: Set up the equation
Let \(n\) be the number of protons. The total mass of \(n\) protons can be expressed as:
\[
