What is the concentration (in milligrams per milliliter) of a solution of KH2PO4 if 250mL of it can be used to prepare 1.0L of a 0.50 mg/mL solution? 2 mg/mL

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.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
