What is the Avogadro Constant? Similarly, as the molecular weight of H2O or water is 18, the mass of one mole of water is 18g. This provides another useful relation, which allows us to calculate the mass of one molecule of a substance. Hence, m = M/NA where M is the molecular mass of a substance, and NA is the Avogadro’s number.

MASTERING PHYSICAL CHEMISTRY By-- S.K. Since one mole of gas occupies 22.4 L at STP, the molecular weight of the gas is 30.6 g mol¯1 11.2 L at STP is one-half molar volume, so there is 0.5 mol of gas present. Therefore, the molecular weight is 80.0 g mol¯1 This problem, as well as the two just above can be solved with PV = nRT.

- The mass in grams of one mole of substance is called molar mass. Each element has its own unique molar mass. For example, carbon’s molar mass is 12.011 g/mol, and magnesium’s molar mass is 24.3050 g/mol.he number of grams in the molar mass of an element is the same as the atomic mass. Translating atomic masses into molar masses, you can construct conversion factors that convert between the mass of an element and the number of moles of the element.

The Mole and Avogadro's Constant Applications of the Mole. The mass of a mole of substance is called the molar mass of that substance. The molar mass is used to convert grams of a substance to moles and is used often in chemistry. The molar mass of an element is found on the periodic table, and it is the element's atomic weight in grams/mole (g/mol).
