Question

How many sulfur atoms are there in 5.05 mol of sulfur? express your answer using three significant figures?

Answer 1

Answer:
number of atoms = 3.04111 * 10^24 atoms

Explanation:
One mole of any substance contains Avogadro's number of atoms.
Therefore, to know the number of atoms in "x" moles, all you have to do is multiply the number of moles (x) by Avogadro's number.
In the question, we are given that the number of moles is 5.05 moles
Therefore:
number of atoms = 5.05 * 6.022 * 10^23 = 3.04111 * 10^24 atoms

Hope this helps :)
