Answer:
There is 5.56 g of gold for every 1 g of chlorine
Explanation:
The ratio is the relationship between two numbers, defined as the ratio of one number to the other. So, the ratio between two numbers a and b is the fraction ![\frac{a}{b}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bb%7D)
You know that a compound has 15.39 g of gold for every 2.77 g of chlorine. This can be expressed by the ratio:
![\frac{15.39 g of gold}{2.77 g of chlorine}](https://tex.z-dn.net/?f=%5Cfrac%7B15.39%20g%20%20of%20gold%7D%7B2.77%20g%20of%20chlorine%7D)
The proportion is the equal relationship that exists between two reasons and is represented by: ![\frac{a}{b}=\frac{c}{d}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bb%7D%3D%5Cfrac%7Bc%7D%7Bd%7D)
This reads a is a b as c is a d.
To calculate the amount of gold per 1 g of chlorine, the following proportion is expressed:
![\frac{15.39 g of gold}{2.77 g of chlorine}=\frac{mass of gold}{1 g of chlorine}](https://tex.z-dn.net/?f=%5Cfrac%7B15.39%20g%20%20of%20gold%7D%7B2.77%20g%20of%20chlorine%7D%3D%5Cfrac%7Bmass%20of%20gold%7D%7B1%20g%20of%20chlorine%7D)
Solving for the mass of gold gives:
![mass of gold=1 g of chlorine*\frac{15.39 g of gold}{2.77 g of chlorine}](https://tex.z-dn.net/?f=mass%20of%20gold%3D1%20g%20of%20chlorine%2A%5Cfrac%7B15.39%20g%20%20of%20gold%7D%7B2.77%20g%20of%20chlorine%7D)
mass of gold= 5.56 grams
So, <u><em>there is 5.56 g of gold for every 1 g of chlorine</em></u>
