Question

If you have a 4.00 mole sample of a substance, how many representative particles does this represent?

Answer 1

1 mole ------------- 6.02x10²³ molecules
4.00 moles -------- ( molecules )

molecules = 4.00 x ( 6.02x10²³) / 1

molecules = 2.41x10²⁴ / 1

=  2.41x10²⁴ molecules

hope this helps!

Answer 2

Explanation:

According to Avogadro's number, in 1 mole there are $6.023 \times 10^{23}$ atoms or particles.

Since, it is given that there is 4.00 mole sample of a substance. Therefore, calculate the number of representative particles present in it as follows.

                 $4.00 mol \times 6.023 \times 10^{23}$ atoms/mol

                 = 24.092 atoms

Thus, we can conclude that there are 24.092 atoms in a 4.00 mole sample of a substance.
