DISSOLVING SOLIDS INTO LIQUIDS

The best way to measure the amount of a solid material is usually to weigh it. The best way to find the amount of a liquid is to find the volume. The formula for solutions is: C V = n, where C is concentration in molar, V is the volume in liters, and n is the number of mols of solute. Further, n = m/Fw , where m is the mass and Fw is the formula weight of the solute. Solving for the mass, m = C V Fw. V = n or m = C V Fw
How do you make the solution of a solid in a liquid. First weigh the solid to get the mass. The concentration you want times the volume of solution times the formula weight of the solute will get you the mass of solute you need to weigh. Place the mass of solute in a volume measuring device such as a volumetric flask or a graduated cylinder. Use a small amount of water to dissolve the solute in the volumetric device. Add water to the volume desired and mix.
The act of dissolving a solid into a liquid is a process that happens on the surface of the particles of the solute. The smaller the particles (the larger the surface area) the faster the solute dissolves. Triple-X sugar, called confectioner s sugar, has smaller particles than regular table sugar. Rock candy is just regular table sugar that has been crystallized in large lumps. When you put each crystal size the chemically identical materials in your mouth, which one dissolves faster? The triple-X sugar tastes sweetest because more of it has dissolved in the same short time. (You can only taste dissolved sugar.)
