Dilutions of Solutions Using Molarity in Calculations of Solutions Solution Stoichiometry Solution Concentration Aqueous Reactions > Solution Concentration Free to share, print, make copies and changes. Get yours at edium=direct&utm_source=boundless

Most commonly, a solution's concentration is expressed in terms of mass percent, mole fraction, molarity, molality, and normality. When calculating dilution factors, it is important that the units of volume and concentration remain consistent. Dilution calculations can be performed using the formula M1V1 = M2V2. A serial dilution is a series of stepwise dilutions, where the dilution factor is held constant at each step. Dilutions of Solutions Free to share, print, make copies and changes.

Molar concentration, also called molarity, is the number of moles of solute per liter of solution. Molarity is the most common measurement of solution concentration. Because molarity measurements are mole/L measurements, we often use this unit for stoichiometric calculations to determine the amount of chemical in a given mixture. Do not confuse moles with molarity: molarity is a measure of concentration, while moles are a measure of the amount of substance.

Stoichiometry deals with the relative quantities of reactants and products in chemical reactions. It can be used to find the quantities of the products from given reactants in a balanced chemical reaction, as well as percent yield. To calculate the quantity of a product, calculate the number of moles for each reactant. Moles of a product are equal to the moles of a limiting reactant in one-to- one reaction stoichiometry. To find product mass, moles must be multiplied by the product's molecular weight. In stoichiometric calculations involving solutions, a given solution's concentration is often used as a conversion factor. Solution Stoichiometry Free to share, print, make copies and changes.
