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

May 31, 2018

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

#### Explanation:

To find the number of atoms in the molecules represented by $6 A {g}_{2} S {O}_{4}$

We begin by determining the atoms in one molecule of $A {g}_{2} S {O}_{4}$

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 $6 A {g}_{2} S {O}_{4}$

We know that the coefficient $6$ tells us that there are 6 molecules of Silver Sulfate $\left(A {g}_{2} S {O}_{4}\right)$
So we must multiply the single molecule values by 6

$2 \cdot 6 = 12$ atoms of Ag - Silver
$1 \cdot 6 = 6$ atoms of S - Sulfur
and
$4 \cdot 6 = 24$ atoms of O - Oxygen
