You can view more details on each measurement unit: molecular weight of CH2Cl2 or mol This compound is also known as Methylene Chloride or Dichloromethane. The mole concept, which we will introduce here, bridges that gap by relating the mass of a single atom or molecule in amu to the mass of a collection of a large number of such molecules in grams. A Calculate the molecular mass of the compound in grams from its molecular formula (if covalent) or empirical formula (if ionic). Hydrogen gas (dihydrogen or molecular hydrogen) is highly flammable: 2 H 2 (g) + O 2 (g) 2 H 2 O(l) (572 kJ/2 mol = 286 kJ/mol = 141.865 MJ/kg). \[4.72 \times 10^{24} \: \text{atoms} \: \ce{C} \times \frac{1 \: \text{mol} \: \ce{C}}{6.02 \times 10^{23} \: \text{atoms} \: \ce{C}} = 7.84 \: \text{mol} \: \ce{C}\nonumber \].
