If a sugar compound has 11 oxygen atoms how many hydrogen atoms does it contain

The answer is 22 hydrogen atoms.

This is a simple sugar compound formula Cn (H2O) n

If you have 11 oxygens that means that the second n in the formula will be 11.

Notice that the H (hydrogen) is followed by a 2, that means that the 11 put outside the parenteses will be multiplied by 2.

11 x 2 = 22 hydrogen atoms

Since simple sugars follow the Cn (H2O) n formula, if you had 11 oxygen atoms, this would produce the simple sugar formula of C11H22O11. Therefore, there should be 22 hydrogen atoms.
