Answer 2

In order to go about this problem, you'll first need to find the moles of Mn in that amount of atoms. You can find the moles by dividing the amount of atoms by Avogadro's number, 6.02 x 10^23.

[6.12 x 10^24 atoms] / [6.02 x 10^23 moles/atoms] = 10.2 moles Mn

Next multiply the moles of Mn by its molar mass, 54.94. The molar mass of a substance the mass of 1 mole of that substance.

10.2 mol x 54.94 grams/mol = 558. grams

So about 558 grams of Manganese.
