Question

How many atoms of each type are in SIX formula units of `Ag_2SO_4`?

Answer 1

Silver - Ag = 12 atoms
Sulfur - S = 6 atoms
Oxygen - O = 24 atoms

Explanation:

To find the number of atoms in the molecules represented by `6Ag_2SO_4`

We begin by determining the atoms in one molecule of `Ag_2SO_4`

We look at the subscripts of the molecule and determine that there are

2 atoms of Ag - Silver
1 atom of S - Sulfur
and
4 atoms of O - Oxygen

Since the original situation is `6Ag_2SO_4`

We know that the coefficient `6` tells us that there are 6 molecules of Silver Sulfate `(Ag_2SO_4)`
So we must multiply the single molecule values by 6

`2*6 = 12` atoms of Ag - Silver
`1*6=6` atoms of S - Sulfur
and
`4*6=24` atoms of O - Oxygen
