››More information on molar mass and molecular weight. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. Compound states [like (s) (aq) or (g)] are not required. You can use parenthesis or brackets []. How To Balance Equations

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) 몰질량은 (molar weight) 어떤 물질이 1몰 있을때의 질량을 이야기 하고 단위는 g/mol입니다. The molecular weight of a substance is the total weight of all atoms present in the compound. Oxygen, for example, has a molecular weight of 31.999 g/mol, while carbon dioxide has a molecular weight of 44.01 g/mol. Under similar conditions, oxygen diffuses faster than carbon dioxide.
