Do this by looking up the atomic mass of each element in the molecule from the periodic table and adding up the masses of all of the atoms. Then, multiply the number of molecules by the molar mass. Divide this value by Avogadro's number to get the mass in grams of the molecules. darood sharif audio mp3 download
