relative ‘molecular’ mass. However, the principle is the same: add the relative atomic masses of sodium (23) and chlorine (35.5) to give 58.5, the relative formula mass of NaCl. Remeer: relative atomic mass, molecular mass and formula mass have no units.
Percent Concentration - Chemistry | Socratic
However, if we keep the mass of the solute at 10.0g and doubled the mass of the solvent (in this case, water), the concentration will be #c% = (10.0g)/(10.0g + 2*100.0g) * 100% = 4.76%# The same is true for percent concentration by volume, which is defined as the volume of the solute divided by the total volume of the solution and multiplied by 100%.
