Step 4: Check

Follow sig fig rules and round. We are given 3 sig figs.

11.2919 mol Ba(NO₃)₂ ≈ 11.3 mol Ba(NO₃)₂

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.
