Answer:
3 different types of atoms.
Explanation:
According to the information provided in this question, one methanol molecule is made up of a carbon atom (C) attached to 3 hydrogen atoms (H) and a hydroxide group (OH). An hydroxide is in turn composed of one hydrogen atom and one oxygen atom. This means that a methanol molecule has the chemical formula; CH3OH.
Based on this chemical formula, a methanol molecule (CH3OH) is composed of three (3) different types of atoms namely: carbon (C) atom, hydrogen (H) atom, and oxygen (O) atom.
