Below is a section of the technical sheet of the resin used in the laboratory for the ion exchange practice. As part of the previous calculations of the practice, you are asked to determine the amount of NaCl solution that you are going to use in the practice, assuming that:The column has an effective length of $0\mathrm{.}2$ meters and a diameter of $0\mathrm{.}0249$ meters and the volume of the column is the volume of the resin $($there are no empty spaces$)$The concentration of the salt used will be $1900$ ppm

Answer the following:

a$)$ Amount of solution in liters $($L$)?$

b$)$ If the work flow is selected at $5$ m$/$h: how long $($minutes$)$ would the saturation of the column be theoretically reached?
