How do you solve solution concentration problems?
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.What are the 3 types of concentration of solution?

The concentration of the solution tells you how much solute has been dissolved in the solvent. For example, if you add one teaspoon to two cups of water, the concentration could be reported as 1 t salt per 2 c water. The vinegar label will report that the solution is 5% by weight acetic acid.- Hence concentration of solution is 4.76%
