number of atoms in 2.0*10^6mol of carbon

Answer 1

Avogadro's number represents the number of particles in one mole of a substance. The value of Avogadro's number is 6.022 x 10^23.

To calculate the number of atoms in 2.0 x 10^6 moles of carbon, we need to multiply the number of moles by Avogadro's number:

2.0 x 10^6 mol x 6.022 x 10^23 atoms/mol = 1.2044 x 10^30 atoms

Therefore, there are approximately 1.2044 x 10^30 atoms in 2.0 x 10^6 moles of carbon.
