The term "mole" is defined in that one mole of a substance with a molecular (or atomic) mass of one (1), will have a mass of 1 gram. Key Takeaway. 1 Answer Meave60 Nov 28, 2015 The molecular formula is #"C"_2"H"_4"#. Played 82 times. The mass of one mole of the fundamental units (atoms, molecules, or groups of atoms that correspond to the formula of a pure substance) is the ratio of its mass to 1/12 the mass of one mole of C-12 atoms, and being a ratio, is dimensionless. Molar mass divided by \(1\ \text{g mol}^{-1}\) (the latter is sometimes called the standard molar mass). Molar Mass Calculator is a free online tool that displays the molar mass of the chemical compound. Molar Mass DRAFT. The molar mass is a physical property, which is defined as the mass of a substance divided by its amount of substance in moles. Make sure you enter the molecule of crystallization at last (e.g. 43% average accuracy. 0. C2HCl3O.H2O ). miniDAWN and microDAWN have 3 angular detectors; they cover a molar mass range of 200 to 10 7 g/mol (10 6 g/mol for linear polymers), and a size range of 10 to 50 nm.
