How many atoms are in corn syrup?

The answer is: a very large number.

Explanation:

Corn syrup is produced through a process called hydrolysis. This involves the breakdown of starch, a large complex sugar, into smaller, more simple sugars such as glucose and fructose. Typically the breakdown is of cornstarch, though other starches such as brown rice starch can also be used. The product is a thick sweet liquid that contains water and multiple simple sugars.

Since its molecular composition varies, the number of atoms in a molecule of corn syrup also varies. However, considering that even a small amount of corn syrup contains a vast quantity of molecules, it is safe to say that the total number of atoms present in any sample of corn syrup is extremely large.
