Molecular Weight Calculator - BOC Sciences

Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. 1 mol consists of exactly 6.02214076 * 10 23 molecules. Relative equations: MW= N 1 xMW 1 +N 2 xMW 2 +N 3 xMW 3 +…+N n xMW n. Note: N n means the nuer of relative element. The molecular weight of elements refers to periodic table of elements.

Molecular Weight Formula - Meaning, Calculation and …

Typically, the molecular weight formula gives the value in units of amu or Da. Here, amu is the atomic mass unit and Da is Dalton. Both the atomic weight and the molecular weight are defined with respect to the mass of isotope of carbon - 12. This isotope has an assigned value of 12 amu and is thus regarded as standard. The molecular weight in turn helps you in knowing how …
