# A compound contains only an unknown metal and chlorine. If analysis shows 41.65 grams of the compound contain 14.18 grams of chlorine, what is the % of the metal in the compound?

The percentage of the metal in the chlorine-containing compound is $\text{65.95%}$.

#### Explanation:

To find the percentage of the metal, first determine the difference between the mass of the compound and the mass of chlorine. This will give the mass of the metal. Divide the mass of the metal by the total mass of the compound and multiply by 100.

$\text{41.65 g"-"14.18 g"="27.47 g}$

The mass of the metal in the compound is $\text{27.47 g}$.

Divide the mass of the metal by $\text{41.65 g}$ and multiply by 100.

(27.47 color(red)(cancel(color(black)("g"))))/(41.65 color(red)(cancel(color(black)("g"))))xx100="65.95%

The percentage of the metal in the chlorine-containing compound is $\text{65.95%}$.
