How many atoms are in a 341g sample of scandium?

Answer 1

341 grams scandium (1 mole Sc/44.96 grams)(6.022 X 1023/1 mole Sc)

= 4.57 X 1024 atoms of scandium

=====================

Answer 2

To find the number of atoms in a sample of scandium, you need to first calculate the number of moles using the molar mass of scandium (44.96 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. 341g of scandium is approximately 7.58 moles, which corresponds to 4.57 x 10^24 atoms.
