According to the Avogadro’s law I mole of any substance contains = 6.023 x 1023
Number of molecules in one mole= 6.023 x 1023
Therefore number of molecules in 6.7 moles of AlCl3:
6.023x1023 molecules /1.0 mole * 6.7 mole
= 40.3541 x 1023 molecules
= 4.03541 x 1024 molecules
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!
