Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a white crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising hydrochloric acid with calcium hydroxide. Calcium chloride is commonly encountered as a hydrated solid with generic for… WebThe heat energy released when new bonds are made between the ions and water molecules is known as the hydration enthalpy of the ion. The hydration enthalpy is the enthalpy change when 1 mole of gaseous ions dissolve in sufficient water to give an infinitely dilute solution. Hydration enthalpies are always negative. WebAnd the molar mass (MM) is equal to the total mass in amu, so the molar mass of water is 18.016 g/mol. 15. 20g of CaCl2 is enough to dissolve in 56L.What is the molarity? The answer is 3 M or 3 mol/L solution: MCaCl2= wt* solute/(MM* solute)(L of solution) Note: pete from goofy
