Hydrogen sulfide, H2S has a molar mass of  34.08088g/mol.
A mol is an expression of the molair weight of a molecule, derived from the weight of a hydrogen molecule, which is 1 mol. Hydrogen has a relative atomic mass of 1 g/ mol and oxygen has a relative atomic mass of 16 g/ mol. Water consists of one oxygen atom and two hydrogen atoms. This means that the mass of a water molecule is 1g + 1g + 16g = 18 g/ mol. When the number of moles of water is known, one can calculate how many grams of weight this is, by using the molar weight of water. The molair weight of separate atoms can be found in the periodic table of Mendelejef.
