Question: I can't understand how to find concentration.
Answer: Concentration is usually measured in "molarity", or "moles/liter". To find the concentration of a solution, determine how many moles of solute are present and find the total volume of the solution you're finding the molarity for. To find moles, you'll need to convert from grams using the molar mass of the compound. To find volume, simply measure with a graduated cylinder.
