Concentrations of solute in solvent, whether in saturated solutions or not, can be expressed in many ways (molarity, molality, ppm, percent by mass, etc.). Molarity = moles of solute / liter of solution molality = moles of solute / kg of solvent ppm = mg solute / liter of solution ppb = microgram of solute / liter of solution %-by-mass = (grams of solute / grams of solution) x 100% To convert from %-by-mass to Molarity, assume 100g of solution,...
