Question

The calculator displayed the number 6.0225. What is the number of molecules in 100 moles in scientific notation? (1 point)
•
6.02 × 1025
O 6.02 × 25
• 6.02 + 1025
• 25 × 106.02

Answer 1

The number of molecules in 100 moles can be calculated using Avogadro's number, which is approximately \(6.022 \times 10^{23}\) molecules per mole.

To find the total number of molecules in 100 moles, you multiply:

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

The correct answer in scientific notation is:

6.02 × 10^25.
