What is the mass in grams of 1.02 x 1024 atoms manganese (mn)? a. 0.112 x 101 g c. 9.30 x 10-1g b. 0.169 x 101 g d. 9.31 x101 g select the best answer from the choices provided a b c d

Option (d) is the correct answer.

Explanation:

According to Avogadro's number, every 1 mole of a substance contains atoms or particles.

Now, it is given that there are atoms of manganese are present. Hence, calculate its number of moles as follows.

     No. of moles =

                           = 1.69  mol

As we know that, number of moles is equal to mass of a substance divided by its molar mass. Since, molar mass of manganese is 54.93 g/mol.

        No. of moles =

                1.69 mol =

                 mass = 93 g

Therefore, we can conclude that the mass in grams of atoms of manganese (Mn) are .

i'm pretty sure it is letter c.) car
