If you also join us at http://www.unicoos.com it will be great!. #seeyouinclass We will do an exercise of CHEMISTRY of baccalaureate, in this case of SOLUTIONS. From the percentage by mass and the density of a sulfuric acid solution, we obtain the Molarity (M), molality (m), mole fraction of the solute and the concentration in grams per liter (gr/l). For this we must assume that we have a liter of solution, with which we can obtain the grams of solution and solvent (water). In the last section we are asked to calculate the volume of the bottle that we must use to prepare another 100 ml solution with a different concentration.

If I put the example of the MILK and the COLACAO it is not because it was a solution, properly speaking, but because I wanted to look for an example that you visualized quickly. In the background is an example of SUSPENSIONS, heterogeneous mixtures, which when they are at rest settle, can be separated by filtration, are cloudy and whose particles are visible to the naked eye. DISSOLUTIONS, on the other hand, are homogeneous mixtures with a particle size equal to one atom (1 to 10 nanometers), translucent, do not settle at rest and can not be separated by filtration. Between both, the COLOIDS that differ from the SOLUTIONS in that their particles are from 10 to 100 nanometers in diameter.
