Question

How many atoms are present in 10 moles of helium???

Answer 1

Avogadro's number: Avogadro's number is the number of atoms in one mole of a substance. The number is 6.022 x 10^23 atoms/mol. So, if you have 1 mole of carbon atoms, there will be 6.022 x 10^23 atoms in that sample.

Answer 2

1 mole of helium has atoms =6*10^23

10 moles will have=6*10^23*10

                              =6*10^24 atoms
