Answer:
The correct answer is skeleton equation.
Explanation:
In chemistry, the skeletal formula of a compound is an abbreviated representation of its molecular structure. Skeleton formulas are used because they clearly show complicated structures, they are fast and simple to draw. 
All atoms that are not carbon or hydrogen are represented by their chemical symbol. The relative amounts of reagents and products are not indicated.
Have a nice day!

Hi there! 
A mole is a type of unit measurement for an amount of a substance like in your cast, salt. 
One mole of salt will be the equivalent to 58 grams
Hope this helped!~
