Find the Mass Percentages Ag

$A g$

Step 1

To find the mass of $1$ mole of $A g$ look up the atomic mass of each element and multiply it by the number of atoms contained in each element in the molecule.

mass of $1$ mole of $A g$ $=$ $(mass of Ag)$

Step 2

Fill in the atomic masses from the periodic table.

mass of $1$ mole of $A g$ $=$ $(107.87000274)$

Step 3

Remove parentheses.

mass of $1$ mole of $A g = 107.87000274 g$

Step 4

Find the mass percentage of $A g$ .

The mass composition percentage is the mass of $A g$ divided by the mass of the entire molecule converted to a percentage.

Mass percentage of $A g = \frac{107.87}{107.87000274} \cdot 100$

Divide $107.87$ by $107.87000274$ .

$0.99999997 \cdot 100$

Multiply $0.99999997$ by $100$ .

$99.99999745$

Set the number as a percent.

Mass percentage of $A g = 99.99999745 %$
