225. 5 grams of Scandium
Explanation:
First we have to divide the given number of atoms [tex](3.02\times10^2^4)[/tex] by the Avogadro's number [tex](6.022\times10^2^3)[/tex], so that we will get the number of moles as 5.
Then the 5 moles of Scandium is multiplied by the molar mass of Scandium which is 44.96 g/mol, we will get the mass of Scandium as 225.5 grams.
So the mass of the Scandium obtained is 225.5 grams.
