What is the molecular mass of ATP?

ATP, or adenosine triphosphate, is a nucleotide that plays a crucial role in cellular metabolism as the primary energy currency of cells. The molecular formula of ATP is C10H12N5O13P3, which, when calculated, gives a molecular mass of approximately 507 g/mol. This value is a result of summing the atomic masses of all the constituent atoms: carbon, hydrogen, nitrogen, oxygen, and phosphorus. The correct choice reflects the accurate molecular weight of ATP, confirming its significance in biochemical processes, such as energy transfer. Other options either underestimate or significantly overestimate the mass of ATP, which is commonly accepted to be around 507 g/mol.
