Molecular weight of co2!
Is molecular weight the same as molar massMolecular Weight Definition
Molecular weight is a measure of the sum of the atomic weight values of the atoms in a molecule. Molecular weight is used in chemistry to determine stoichiometry in chemical reactions and equations.
Molecular weight is commonly abbreviated by M.W. or MW. Molecular weight is either unitless or expressed in terms of atomic mass units (amu) or Daltons (Da).
Both atomic weight and molecular weight are defined relative to the mass of the isotope carbon-12, which is assigned a value of 12 amu.
The reason the atomic weight of carbon is not precisely 12 is that it is a mixture of isotopes of carbon.

Sample Molecular Weight Calculation
The calculation for molecular weight is based on the molecular formula of a compound (i.e., not the simplest formula, which only includes the ratio of types of atoms and not the number).
The number of each type of atom is multiplied by its atomic weight and then added to the weights of the other atoms.
For example, the molecular formula of hexane is C6H14. The subscripts indicate the number of each ty
