The common eastern mole, a mammal, typically has a mass of 83 g, which corresponds to about 8.3 moles of atoms. (a mole of atoms is 6.02 × 1023 atoms. in atomic mass units (u), what is the average mass of atoms in the common eastern mole?

1.6605 × 10⁻²³ g / atom , 9.99 amu

Explanation:

Atoms present in 1 mole = 6.022 × 10²³ atoms

Given that

Moles of common Eastern mole = 8.3 moles

So,

Atoms in 8.3 moles are:

8.3 moles = 6.022 × 10²³ × 8.3 atoms

Also,

Average mass = Mass of the sample / Number of atoms

Mass of sample = 83 g

Average mass = 83 g / 6.022 × 10²³ × 8.3 atoms = 1.6605 × 10⁻²³ g / atom

In amu :

1 amu = 1.66 × 10⁻²⁴ g / atom

So,

Average mass = 1.6605 × 10⁻²³ / 1.66 × 10⁻²⁴ amu = 9.99 amu
