A hypotonic solution in which it contain more solute than solvent.example a lot of salt (solute)
dissovled in water (solvent)
isotonic solution in which solute and solvent are equally distrubuted for example a cell normally wants to remain in an isotonic solution where concentration of liquid inside it is equal to the concentration of the liquid outside of it.
hypertonic solution in which contains more solvent than solute.
Calculate (a) molality (b) molarity and (c) mole fraction of KI if the density of 20% (mass/mass) aqueous KI is 1.202 g mL-1.
Molality (m) is defined as the number of moles of the solute per kilogram (kg) of the solvent and is expressed as:
Molarity (M) is defined as number of moles of solute dissolved in one litre (or one cubic decimetre) of solution.
(a) Mol. mass of
Volume of solution = 4.3 L
(b) Number of moles present in 1000 ml of 0.5M H2SO4= 0.5 mol
therefore number of moles present in 30ml of 0.5M H2SO4=mol =0.015mol
therefore molarity =0.015/0.5L
thus molarity is 0.03M
