In chemistry class, Carlos calculated the number of molecules in 100 miles. The calculator displayed the number 6.02E25. What is the number of molecules in 100 moles in scientific notation?

Answer 1

The number of molecules in 100 moles can be calculated by multiplying the number of moles by Avogadro's constant (6.02 x 10^23).

Therefore, the number of molecules in 100 moles is:

100 moles * 6.02 x 10^23 molecules/mole = 6.02 x 10^25 molecules.

Thus, the number of molecules in 100 moles in scientific notation is 6.02E25.
