Chapter 5.1, Problem 72E

To determine

To write:TheAvogadro’s number, $6\cdot 02\times {10}^{23}$ in standard form.

Answer to Problem 72E

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

Explanation of Solution

Given: The number is $6\cdot 02\times {10}^{23}$ .

Calculation:

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

Therefore,

  $6\cdot 02\times {10}^{23}$

  $=6\cdot 02\times 1000\times 1000\times 1000\times 1000\times 1000\times 1000\times 1000\times 100$

  $=602,000,000,000,000,000,000,000$

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