A concentrated solution has a greater amount of dissolved solute than a dilute solution.
A solution is a homogeneous mixture that contains one or more solutes dissolved in a . A concentrated solution has more dissolved than a dilute solution. Two ways to indicate the concentration of a solution are mass percent and , M.
Mass percent is determined by dividing the mass of the solute by the total mass of the solution, then multiplying times 100. For example, if a 125 g NaCl solution contains 25 g of the solute NaCl, the mass percent = ##(25 "g" "NaCl")/(125 "g" "NaCl sol'n")xx100=20% "NaCl"##.
Molarity is mol/L, and is determined by dividing the moles of a solute by the volume of the solution in liters. If you have a solution containing 0.35 mol of the solute NaCl dissolved in a 1.5 L solution, then ##(0.35 "mol NaCl")/(1.5 "L NaCl sol'n")## = ##"0.2 mol NaCl/L"## = ##"0.2 M NaCl"##, which is read as 0.2 molar sodium chloride solution.
