What is the molality of a solution made by dissolving 2 moles of NaOH in 6 kg of water?
O A. 0.33 mol/kg
B. 12 mol/kg
O C. 2 mol/kg
O D. 3 mol/kg

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
