Answer: The correct answer is the ratio of oxygen atoms to hydrogen atoms in a molecule of sugar is 2 to 1.
Step-by-step explanation:
The given chemical formula for table sugar is
.
The above compound contains 12 atoms of carbon atom, 11 atoms of hydrogen and 22 atoms of oxygen.
The ratio of oxygen atoms to hydrogen atoms is
and the ratio of carbon atoms to hydrogen atoms in a molecule of sugar is

An oxygen atom contains 8 protons and a carbon atoms has 6 electrons.
Hence, the correct statement is the ratio of oxygen atoms to hydrogen atoms in a molecule of sugar is 2 to 1.
