Calculating Molar Mass

Calculating Molar Mass. On the periodic table, the atmoic mass given is the mass (in grams) of one mole of that atom. Sodium (Na) Molar Mass = 22.99 g Magnesium (Mg) = ____ g. What about molecules?. NaCl has one of each atom = 23 + 35.5 = 58.5 g in one mole of NaCl H 2 0

IV. Converting between Particles and Mass

IV. Converting between Particles and Mass. The Mole. A . Converting Particles to Mass. Since 6.02 X 10 23 particles = 1 mole AND 1 mole = molar mass (grams) You can convert atoms/molecules to moles and then moles to grams! (Two step process).

Mole

Mole. The mass of a single atom is too small to measure on a balance. E.g. mass of a hydrogen atom = 1.673x10 -24 g An analytical balance can measure up to 4 decimals. To measure atoms in the real world we need a huge number of atoms. That huge # we define as a mole.
