Laboratory Solution Preparation
The most common unit of solution concentration is molarity (M). The molarity of a solution is defined as the number of moles of solute per one liter of solution

How do you prepare a solution for concentration?
Divide the mass of the solute by the total volume of the solution. Write out the equation C = m/V, where m is the mass of the solute and V is the total volume of the solution. Plug in the values you found for the mass and volume, and divide them to find the concentration of your solution.How do you prepare a 3% solution?
Example 1: If you want to make 3% w/v NaCl you would dissolve 3.0 g NaCl in 100 ml water (or the equivalent for whatever volume you needed).How do you make a 5% concentration solution?
To make a 5% solution, take one part by weight of powder and add it to 19 parts by weight of solvent. For example, dissolve 50 grams of sodium carbonate in 950 grams of water. 2. In most circumstances, however, the water will not need to be weighed.- To make a proper 2 percent solution, they should specify a solvent but the general way to make a 2 percent solution is to get 2 grams of solvent and dissolve it in 98-100 ml of water.
