There are 5.35 × 10²⁴ atoms in 8.89 moles of Helium.
<u>Explanation:</u>
Given that number of moles of Helium = 8.89 moles
Moles and Avogadro's number are related to each other by multiplying those two we can convert moles into atoms, molecules and Particles .
We have to convert the moles into atoms by multiplying the molar amount by Avogadro's number as,
Number of atoms = 8.89 × 6.022 × 10²³ atoms
= 5.35 × 10²⁴ atoms
So there are 5.35 × 10²⁴ atoms in 8.89 moles of Helium.
