Answer:
The percent composition of fluorine is 65.67%
Explanation:
Percent Composition is a measure of the amount of mass an element occupies in a compound. It is measured in percentage of mass.
That is, the percentage composition is the percentage by mass of each of the elements present in a compound.
The calculation of the percentage composition of an element is made by:
![percent composition element A=\frac{total mass of element A}{mass of compound} *100](https://tex.z-dn.net/?f=percent%20composition%20element%20A%3D%5Cfrac%7Btotal%20mass%20of%20element%20A%7D%7Bmass%20of%20compound%7D%20%2A100)
In this case, the percent composition of fluorine is:
![percent composition of fluorine=\frac{39.6 g}{60.3 g} *100](https://tex.z-dn.net/?f=percent%20composition%20of%20fluorine%3D%5Cfrac%7B39.6%20g%7D%7B60.3%20g%7D%20%2A100)
percent composition of fluorine= 65.67%
<u><em>The percent composition of fluorine is 65.67%</em></u>
Answer:
6
Explanation:
Normally, oxygen has 8 electrons and 8 protons. If the charge is 2-, then that means there are two more protons than electrons. There would be 6 electrons.
