Question

Responses

25×10 to the power of 6.02
25 times 10 superscript 6.02 baseline

6.02×10 to the power of 25
6.02 times 10 superscript 25 baseline

6.02+10 to the power of 25
6.02 plus 10 superscript 25 baseline

6.02×25

Answer 1

The number of molecules in 100 moles is calculated using Avogadro's number, which is approximately \(6.02 \times 10^{23}\) molecules per mole. Therefore, in 100 moles, the number of molecules is:

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

So the correct response is:

6.02×10 to the power of 25
