How many sulfur atoms are in 78.4 grams of sulfur?

Answer 1

I rounded up to 1.47 X 10^24 atoms of Sulfur in 78.4 grams Sulfur


78.4 grams X (1 mole S/32.07 g S) X (6.02 X 10^23 atoms S/ 1 mole) = 1.472 X 10^24 atom


Taking significant digits into account (3 sig. figs.), I get 1.47 X 10^24 atoms S

Answer 2

To determine the number of sulfur atoms in 78.4 grams of sulfur, you first need to convert the mass to moles using the molar mass of sulfur (32.06 g/mol). Then, you can use Avogadro's number (6.022 x 10^23) to find the number of atoms in that quantity of moles.
