Question

In chemistry class, Carlos calculated the number of molecules in 100 moles. The calculator displayed the number 6.02E25. What is the number of molecules in 100 moles in scientific notation?(1 point) Responses 6.02×25 6.02 times 25 25×106.02 25 times 10 superscript 6.02 baseline 6.02×1025 6.02 times 10 superscript 25 baseline 6.02+1025

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.

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

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

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

6.02 × 10²⁵
