The formula of copper sulfate crystals is CuSo4.5H2O. 400ml of 0.02mol/l copper (ii) sulfate solution is needed to be prepered . a. calculate the molar mass of the solute .
b. calculate the mass of the solute that sould be weighted to prepare this solution .
c. describe in details the steps of preperation of the solution​

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.

it's c. elements are placed in rows based on how may valencies electrons have.

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.
