Question

A common number used for calculations in chemistry is Avogadro’s number, which is approximately equal to $6.02\times {10}^{23}$. Write this number in standard form.

Short answer

The standard form of Avogadro’s number is $602,000,000,000,000,000,000,000$.

Step-by-step solution

Step 1. Given information

The number is $6.02\times {10}^{23}$.

Step 2. Calculation 

To write the Avogadro’s number in standard form shift the decimal 23 places towards the right from its current position.

Therefore,

$\begin{array}{c}6.02\times {10}^{23}=6\times 02\times 1000\times 1000\times 1000\times 1000\times 1000\times 1000\times 1000\times 100\\ =602,000,000,000,000,000,000,000\end{array}$

Thus, standard form of Avogadro’s number is $602,000,000,000,000,000,000,000$.
