How many sulfur atoms are in 0.45 mol baso4? ?

Explanation:

According to the mole concept, there are atoms present in one mole.

As it is given that number of moles of are 0.45 mol.

Therefore, there is only one atom of sulfur. Hence, calculate atoms of sulfur as follows.

                atoms

                      = atoms

Thus, we can conclude that there are atoms of sulfur in 0.45 mol .

that's what i got you can count the number of atoms
