The formula mass (formula weight) of amolecule is the sum of the atomic weights of the atoms inits empirical formula. The molecular mass(molecular weight) of a molecule is its average massas calculated by adding together the atomic weights of theatoms in the molecular formula.

That is, the molar mass of a substance is themass (in grams per mole) of 6.022 × 10 23atoms, molecules, or formula units of that substance. Ineach case, the number of grams in 1 mol is the same as the numberof atomic mass units that describe the atomic mass,the molecular mass, or the formula mass,respectively.

Subsequently, question is, what is the difference between molecular weight and exact mass? Actually there is no difference between molecularweight and exact mass. In same way, weight of themolecule / atom can be expressed in atomic mass unit(amu or u) or actual/exact mass (i.e mass expressedin kg). If we express the mass of a molecule in amuthen we call it molecular mass/weight.

Just so, what is the formula of molar mass?

The molar mass is the mass of a givenchemical element or chemical compound (g) divided by the amount ofsubstance (mol). The molar mass of a compound can becalculated by adding the standard atomic masses (in g/mol)of the constituent atoms.

How do you convert molar mass to Grams?

There are three steps to converting moles of a substance tograms:

  1. Determine how many moles are given in the problem.
  2. Calculate the molar mass of the substance.
  3. Multiply step one by step two.
