Converting Grams to Moles Chemists physically measure the mass of substances using an analytical balance. An analytical balance measures grams; it cannot count moles, amus, or the number of particles in a sample. This is why scientists need a way to know how to convert from grams to moles....
Converting Between Moles and Mass Millicent McAlpin May 22, 2013 Chemistry honors THE MOLAR MASS Mole: a unit used in counting - According to Avogadro’s number =6.02 x 10^23 Molar Mass: is the same is the atomic number of an element on the periodic table. Mass of 1 mole: -Na= 23 ...
