Step 1:
I'll solve this problem step by step, following the specified LaTeX formatting guidelines:

Step 2:
: Recall the fundamental definition of elementary charge

The elementary charge ($$e$$) is the magnitude of electric charge carried by a single proton or electron.
This is a fundamental physical constant.

Step 3:
: Recall the value of elementary charge

The elementary charge is $$e = 1.602 \times 10^{-19}$$ coulombs.

Step 4:
: Set up the calculation to find the number of elementary charges

N = \frac{1 \mathrm{~C}}{1.602 \times 10^{-19} \mathrm{~C}}
To find the number of elementary charges in 1 coulomb, we need to divide the total charge by the charge of a single elementary charge.

Step 5:
: Perform the division

N = \frac{1}{1.602 \times 10^{-19}} = 6.241 \times 10^{18}

Final Answer

The number of elementary charges in 1 coulomb is 6.241 \times 10^{18} elementary charges. Key Insight: This calculation demonstrates how many fundamental electric charges are required to make up one coulomb of charge, highlighting the incredibly small size of the elementary charge.
