Answer 1

heya..

mate...

here is your answer...

Count how many atoms of each element exist in the molecule. First, list each element present in the molecule. You may use the chemical symbol or write out the name of the element. Then, count the atoms according to the molecular formula and write them next to the element’s name or symbol.[2]

For example, carbon dioxide or CO2, list that there is 1 carbon (C) and 2 oxygens (O) present in the molecule.

For methane, CH4, list carbon (C) and hydrogen (H). Methane comprises 1 atom of carbon and 4 atoms of hydrogen.

For glucose, C6H12O6, list carbon (C), hydrogen (H), and oxygen (O). Glucose comprises 6 atoms of carbon, 12 atoms of hydrogen, and 6 atoms of oxygen.
