6.02×10
25

Answer 1

To find the number of molecules in 100 moles, you can use Avogadro's number, which is approximately \( 6.02 \times 10^{23} \) molecules per mole.

So, to calculate the number of molecules in 100 moles, you multiply:

\[ 100 , \text{moles} \times 6.02 \times 10^{23} , \text{molecules/mole} = 6.02 \times 10^{25} , \text{molecules} \]

Therefore, the number of molecules in scientific notation is:

\[ 6.02 \times 10^{25} \]

So the correct answer is:

6.02 × 10\(^25\).
