Chemists routinely perform calculations of the amount of substances necessary to carry out a chemical reaction. Textbooks refer to this topic as "stoichiometry." Chemists base all stoichiometric calculations on moles. A mole represents 6.022 x 10^23 for
To find the molar mass of NaCl, you add the mass of each element. Work out 22.9898 + 35.4530 = 58.4538.Moles of Solute Say you create a solution with 200 grams of table salt. One mole equals the molar mass of the solute which is 58.4538 grams. Divide the mass of the solute by the...
