Given information

Given: 

Compound = Nitrogen triiodide

Find:

1. Chemical formula of compound =?

2. Mass percentage of each component =?

Step-by-step explanation

Step 1.

Conceptual plan:

A. Steps to determine the chemical formula of covalent compounds.

  1. The first element is listed as the first word of the name.
  2. The second element is named as the base word with the suffix "ide".
  3. Some time prefix is also used with the name of first or second element which represents the number of elements as:
mono   hexa    
di   hepta    
tri   octa   
tetra   nona   
penta   deca  

*If there is one atom of the first element is present then the prefix "mono" is omitted with its name.

B. Steps to determine the mass percent of each element :

  1. Determine the molar mass of of compound.
  2. Find the mass percent of each element by using the formula.
