How many atoms of mg are present in 97.22 grams of mg? 6.022 × 1023 2.408 × 1024 4.818 × 1024 5.855 × 1025

Option (b) is the correct answer.

Explanation:

It is given that mass of Mg is 97.22 g and it is known that molar mass of Mg is 24.305 g/mol.

So, calculate the number of moles as follows.

          No. of moles =

                                 =  

                                 = 4 mol

Also, it is known that 1 mole has atoms/mol. Therefore, calculate the number of atoms in 4 mol as follows.

               = atoms

or,            = atoms

Thus, we can conclude that there are atoms in 97.22 grams of Mg.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
