How many oxygen atoms are present in 3 grams of glucose 6.022 x 10^22
3.31 x 10^22
3.31 x 10^23
6.022 x 10^23

Because CLEARLY, each mole of glucose, C6H12O6 contains 6⋅mol oxygen atoms.

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.
