How many moles of helium atoms are there in 4.0 x 1024 helium atoms?

There are 6, 64 moles of helium atoms.

Explanation:

We use Avogadro's number, according to which in 1 mole of any substance there are 6,023 x 10 e23 particles (example: atoms, molecules). We calculate the number of moles according to the following simple three rule:

6,023 x 10 e23 atoms1 mol Helium

4.0 x 10e 24 atomsx=

x= (4.0 x 10e 24 atomsx1 mol Helium)/6,023 x 10 e23 atoms=

x=6, 64 moles of Helium

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
