Question

In this experiment you will be using an aqueous solution of copper sulfate as a source of copper ions. To prepare this solution we normally use a hydrated form of copper sulfate, copper sulfate pentahydrate or CuSO4·5H2O, because the anhydrous form, CuSO4 is more expensive. The formula CuSO4·5H2O indicates that each mole of hydrated salt contains one mole of copper sulfate and 5 moles of water, and the molar mass of the pentahydrate is the sum of the masses of the components. To determine the heat of the reaction, you will need to know the starting concentration of this solution. Concentration of a solution is often expressed as molarity or molar concentration, M. It indicates number of moles of solute in one liter of the solution and is measured in mol/L. Knowing mass and molar mass of the solute, one can easily determine number of moles of solute in a certain volume of a solution and from there, the molarity of a solution. What is the molar concentration of the solution prepared by dissolving 500.0 g of copper sulfate pentahydrate in enough water to make exactly 2.5 L of the solution?
