Using the same model kit used for the model of methanol (above), you make a model of ethanol. This is the chemical formula for ethanol. How many dark grey spheres would you use in your model of ethanol?
The chemical formula for ethanol is C2H6O. In the model, each carbon atom is represented by a dark grey sphere. Since there are 2 carbon atoms in ethanol, you would use 2 dark grey spheres in the model.
