i need help with these 2 questions

Which of the following are true? Choose all that apply. When the sports drink is passed through the ion exchange resin, each 1+ charged cation displaces one H+ion, and each 2+ charged cation displaces two H+ions. When the sports drink is passed through the cation exchange resin, the cations react with the resin, producing OH, which is subsequently rinsed from the column. H+ions washed from the resin are titrated with a solution of NaOH of unknown concentration. This allows the analyst to determine the exact concentration of NaOH. When the sports drink is passed through the ion exchange resin, each Cldisplaces one H+. H+ions washed from the resin are titrated with a solution of NaOH of known concentration. This allows the analyst to determine the concentration of cations in the aliquot of unknown added to the column. Three aliquoits of the sports drink were passed through the cation exchange column as described in the procedure. The endpoint volumes were determined to be 36.97mL,36.94mL, and 37.03mL using 0.09820M NaOH. Titration of the sports drink alone resulted in an endpoint volume of 14.79mL. Determine the total molarity of the cations in the sports drink. M
