<span>Colloid is a type of mixture that scatters light and cannot be filtered. Colloids are heterogeneous mixtures with a particle size between that of the solutions and that of the suspensions: the size of the particles of a colloid is bigger than the molecules or ions of a solution and smaller than the particles of a suspension. Due to the small size of the particles in the colloids, the diluted colloids seem homogeneous, but those particles are big enough to produce the Tyndall effect, which is the dispersion of the light. Solutions do not show Tyndall effect.</span>
(a) 485 x 200 mg = 97000 mg of ibuprofen in the bottle
97000 mg x (1g/1000mg) = 97g of ibuprofen in the bottle
97g (1 mol/ 206.5gC13H18O2) = 0.46973 moles of ibuprofen in the bottle
(b) 0.46973 mol C13H18O2 (6.022 x 10^23 molecules/1mol) = 2.8287 x 10^23 molecules of ibuprofen in the bottle
