How to determine molar mass of compound
WebThe molar mass is calculated by measuring the mass and the number of moles in a sample of the substance of interest, and then dividing both amounts: Where m is the mass, n the number of moles and M the resulting molar mass. What is the molar mass Almost all matter on Earth is made of atoms. WebTo calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms. For example, the molar mass of NaCl can be calculated for finding the atomic mass of sodium (22.99 g/mol) and the atomic mass of chlorine (35.45 g/mol) and combining them. The molar mass of NaCl is 58.44 g/mol.
