The subscripts in the molecular formula must equal n times the subscripts in the empirical formula (where n is an integer). Both 10 and 8 are divisible by 2, so the empirical formula is C5H4.
In science, ATP stands for adenosine triphosphate. This chemical, discovered in the 1920s, is important to all life. It stores and releases energy for many cellular processes. It is found in mitochondria.
