Close Probiem Calculate ion concentration. In the laboratory, a student adds 17.7 g of sodium iodide to a 125 mL volumetric flask and adds water to the mark on the neck of the flask, Calculate the concentration (in mol/L) of sodium iodide, the sodium ion and the iodide ion in the solution. [Nal] = M [Na*) = M [r] M Check & Submit Answer Show Approach The concentration of a solution can also be used to determine the volume of a solution that contains a specific amount of solute or the amount of solute in a given volume of solution. That is, a concentration in units of molarity can be used as a conversion factor to convert between the amount of solute in a solution (in moles) and the volume of a solution (in liters). For example, we can calculate the volume of a 0.264 M solution of AgNO3 needed to provide 18.6 g of the ionic compound. First, determine the amount of AgNO3 needed in units of moles. étv hulu
