A balance and a volumetric flask are used to make molar solutions. The amount of water needed will be slightly less than 100 ml. To make 200 milliliters of your solution multiply grams/liter by liters needed. The solute is the chemical(s) that’s less abundant. One of the most common ways to express the concentration of the solution is M or molarity, which is moles of solute per liter of solution. Determine MW using a periodic table by adding the atomic mass of each atom in the chemical formula. The technique used can be applied to any mole to gram conversion. For experiments, you will often need to dissolve solutes in solid form to make solutions of a particular strength (strength is measured by ion disassociation). You prepare a solution by dissolving a known mass of solute (often a solid) into a specific amount of a solvent. For example, "NaCl" dissociates completely in water to form "Na"^+ ions and "Cl"^- ions. The solvent, often water, is the chemical that’s most abundant. You might consider scaling down when experiments call for large amounts of chemical. A mole consists of 6.02×1023 molecules or atoms. An osmole (Osmol) is 1 mol of particles that contribute to the osmotic pressure of a solution.
