You can use any units you wish for the concentration values and volumes, so long as you use the same units for each of the two solutions. Concentration can also be expressed by percent composition by mass, mole fraction, molarity, molality or normality. For example, work out the percent co...
This quiz and corresponding worksheet will help you gauge your understanding of how to calculate molarity and molality concentration. Topics you'll need to know to pass the quiz include understanding the moles of a solute per liter of a solution as well as knowing when molality is usually ...
Molality: Molarity can help in characterizing given solution as dilute or concentrated. High molarity indicates concentrated solution while low molarity indicates dilute solution. Knowing the solution's molarity, it is easy to find solute's mass in given solution's volume. Answer and...

(in units of grams per milliliter, or g/mL) by 1,000 mL (the quantity of milliliters in the 1 liter of solution volume). The result is the mass of the 1 liter of solution, in grams. For the example, if the density of the KCl solution was 1.05 g/mL, you would calculate 1.05...
take 0.05 ml = 50 ul of stock solution and dilute it with 150 ul of solvent to get the 200 ul of 25 mg/ ml solution needed (remember that the amount of solvent used is based upon the final volume needed, so you have to subtract the starting volume form the final to calculate it....

Concentrationis an expression of how muchsoluteis dissolved in asolventin a chemicalsolution. There are multipleunits of concentration. Which unit you use depends on how you intend to use the chemical solution. The most common units are molarity, molality, normality, mass percent, volume percent,...
Learning how to calculate molarity isn't difficult; the key is to remember the units of molarity (M): moles per liter. Find the molarity by calculating the number of moles of the solute dissolved in liters of a solution. Molarity is a unit of concentration, measuring the number of moles ...
