Question

write the molecular formula of methanol. the color codes for the ball - and - stick model shown are: black (carbon), red (oxygen), and white (hydrogen). the order of elements is important.

Explanation:

Step1: Count the number of each atom

• Carbon (black): 1 atom.
• Oxygen (red): 1 atom.
• Hydrogen (white): 4 atoms.

Step2: Write the molecular formula

The molecular formula is written by putting the symbols of the elements and their respective number of atoms as subscripts. So for 1 carbon ($C$), 1 oxygen ($O$), and 4 hydrogens ($H$), the formula is $CH_{4}O$.

Answer:

$CH_{4}O$
