, Calculate the percent by weight of sodium (Na) and chlorine (Cl) in sodium chloride (NaCl). How to Solve the Problem Step 1 - Determine mass of solute Solution: The chemical formula for water is H 2 O. We use this term to signify the total percent by mass of each element that is present in a compound.It is important to note that we can calculate the mass percentage composition by dividing the mass of a component by the total mass of the mixture. total = 78.0036 g/mol. H x 12 x 1.008g/mol = 12.096g/mol Calculate the percent by weight of sodium (Na) and chlorine (Cl) in sodium chloride (NaCl) Calculate the molecular mass (MM): MM = 22.99 + 35.45 = 58.44 ; Calculate the total mass of Na present: How to Calculate Percentage Composition. Percent composition is the term used to describe the percent by mass of each element in a compound. Total = 180.161g/mol = molar mass of glucose. It is typically found using the molar mass values for both the elements in the compound and the compound itself.
