This concentration measurement is called molarity. Molarity is sometimes a challenging concept to understand. However, with your recently acquired solution preparation skills, you will see that making molar solutions required only on extra calculation. To understand how to make a solution of a given molarity, you must know what a “mole” is.
Molar Enthalpy of Solution
Calculate the molar heat ( H) for the dissolving of the three solids. The formula is given below . H substance = m * c * t . n. m = mass of the substance in grams c= specific heat capacity of water (4.18 J/g*oC) t = temperature change in water in calorimeter. Problem: Based on your calculations in your experiment chose one of the salts and ...

A solution is approximately 1 molar in Cu2+ and 1 molar in Zn2+. Based on the data above, outline three different methods for separating them discussing the theoretical bases for these separations. Answer: (1) Add a dilute solution of H2S, or any other soluble sulfide, dropwise to the solution to precipitate the less soluble CuS.
