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)
6.02 + 10 ^ 25;
6.02 * 10 ^ 15;
6.02 * 25;
25 * 10 ^ (6m)
The correct answer is 6.02 * 10 ^ 25.
To calculate the number of molecules in 100 moles in scientific notation, we can use Avogadro's number. Avogadro's number is approximately 6.02 x 10^23, which represents the number of particles (atoms, molecules, or ions) in one mole of a substance.
In this case, Carlos has 100 moles. To determine the number of molecules, we can multiply the number of moles by Avogadro's number:
Number of molecules = 100 moles * 6.02 x 10^23 molecules/mole
Multiplying these values together, we get:
Number of molecules = 6.02 x 10^25 molecules
Therefore, the answer is 6.02 x 10^25 in scientific notation.
