Question

what is meant by the term molecular mass,and how is it calculated?​

Answer 1

Answer:

Molecular mass is a number equal to the sum of the atomic masses of the atoms in a molecule. The molecular mass gives the mass of a molecule relative to that of the 12C atom, which is taken to have a mass of 12.

Molecular mass is the mass of a single molecule, given in atomic mass units (amu). Molar mass is the mass of one mole of a substance, given in units of grams per mole (g/mole).

Determine the molecular formula of the molecule.

Use the periodic table to determine the atomic mass of each element in the molecule.

Multiply each element's atomic mass by the number of atoms of that element in the molecule.This number is represented by the subscript next to the element symbol in the molecular formula.

Add these values together for each different atom in the molecule.
