Need the molecular weight of a revolutionary wonder-liquid? Or a bulky metal–organic framework?

No problem.
From everyday organics to complex solids, MERP makes it easy to sum the elements of a molecule.
Using the calculator, type a formula or tap in the counts of elements to build the molecule. Save the molecule to keep it around and see composition and per-molecule weight.
