Determine the mass in grams of 3.75 x 10^21 atoms of zinc. (the mass of one mole of zinc is 65.39 g)

The mass in atoms of zinc is 0.405 g.

Explanation:

Given: Atoms of zinc =

It is known that 1 mole of every substance contains atoms. So, the number of moles in given number of atoms is as follows.

As moles is the mass of a substance divided by its molar mass. So, mass of zinc (molar mass = 65.39 g/mol) is calculated as follows.

Thus, we can conclude that the mass in atoms of zinc is 0.405 g.
