Hydrogen sulfide, H2S has a molar mass of  34.08088g/mol.
1 Mole = 6.02 x 1023 1 mole of atoms = 6.022 x 1023 atoms 1 mole of molecules = 6.022 x 1023 molecules Molar Mass: the mass (in grams) of one mole a particular substance There is a unique relationship between molar mass and atomic weight: Oxygenâs atomic weight is 16.00 amu. 1 mole of oxygen is 6.02 x 1023 atoms of oxygen 1 amu = 1.661 x 10-24g What is the molar mass (g/mole) of oxygen? 16.00 amu/oxygen atom x 1.661 x 10-24g/amu = 2.657 x 10-24 g/atom x 6.02 x 1023 atoms/mole =16.00 g/mole Molar mass (in grams) is always equal to the atomic weight of the atom! Molar mass (in grams) is always equal to the atomic weight of the atom! Examples: Atomic weight of carbon is 12.01amu Molar mass of carbon is 12.01 g/mol Atomic weight of helium is 4.00 amu Molar mass of helium is 4.00 g/mol Mole (mol): The number of particles (atoms or molecules) in a sample of element or compound with a mass in grams equal to the
