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...
Find the total molecular weight of the substance. By adding up all the weights of all the atoms of the substance we get its molecular weight. For example, water contains two hydrogen atoms at 1.0079 and one oxygen atom at 15.9994. Added together, this equals 18.015 g/mol. Step 4 Divide ...
