Answer 1

To find the number of molecules in 100 moles, you can use Avogadro's number, which is approximately \(6.022 \times 10^{23}\) molecules per mole.

To calculate the number of molecules in 100 moles, you multiply Avogadro's number by 100:

\[ 100 , \text{moles} \times (6.022 \times 10^{23} , \text{molecules/mole}) = 6.022 \times 10^{25} , \text{molecules} \]

So, the correct number of molecules in 100 moles in scientific notation is:

\[ 6.022 \times 10^{25} \]
