The units for molarity, M, are grams of solute Liters of solutiorn moles of solution Liters of solution moles of solute grams of solution moles of solute Liters of solution O
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,...

what volume of a 7.74 M KCl solution would contain 23.6 grams of solute?
Dilution of Concentrated Solutions The number of moles of solute in liters of a solution of molarity is given by Moles Solute = m x v It is often of practical importance to take a concentrated solution of known concentration, and to add solvent to it to obtain a diluted solution with a desired concentration. During the process of dilution, since only solvent is added, the number of moles of solute is constant. Using to denote the concentrated solution, and...
