in chemistry class Carlos calculated the number of molecules in 100 moles that calculate displayed the number 6.0 2E25 what is the number of molecules in 100 moles and scientific notation would it be 6.02+10 power of 25 or 6.02×25 or 25×10 with the power of 6.0 or 6.02×10 power of 25

Answer 1

In chemistry, the number of molecules in a mole is given by Avogadro's number, which is approximately \(6.02 \times 10^{23}\) molecules per mole.

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

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

So, Carlos's calculation of \(6.0 \times 10^{25}\) may have been a slight rounding, but it is indeed expressed in scientific notation. The correct representation of the number of molecules in 100 moles is:

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

Therefore, the correct notation among your options is \(6.02 \times 10^{25}\).
