APPLICATION When chemists write formulas for chemical compounds, they indicate how many atoms of each element combine to form a molecule of that compound. For instance, they write H2O for water, which means there are two hydrogen atoms and one oxygen atom in each molecule of water. Acetone (or nail polish remover) has the formula C3H6O. The C stands for carbon. a. How many of each atom are in one molecule of acetone? b. How many atoms of carbon must combine with 470 atoms of oxygen to form acetone molecules? How many atoms of hydrogen are required? c. How many acetone molecules can be formed from 3000 atoms of carbon, 3000 atoms of hydrogen, and 1000 atoms of oxygen?
