A Dalton is a unit of atomic mass equal to the mass of 112 of a particle of carbon C.One mol contains exactly 6.0221407610 elementary particles (this number is called the Avogadros Number ).
When we use gmol, we describe the weight of one mole of a given substance. Although their values are identical, they describe different quantities. Thats why we use the combined gas law calculator (a.k.a. PV-NRT calculators). Depending on a process, you may also cross out one of the following variables: T, V, P. C22H30N4O c22h30n40 Instructions to calculate molar mass (molecular weight) of a chemical compound: To calculate molar mass of a chemical compound, please enter its chemical formula and click Calculate. Definitions of molecular mass, molecular weight, molar mass and molar weight: Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). Molar mass (molar weight) is the mass of one mole of a substance and is expressed in gmol.
