Asked by Jon
1.) A biochemistry student wants to make 4 liters of a phosphate solution using 48.6 g Na2HPO4 (FW=141.96) What is the concentration of this solution?
2. When she reaches the storeroom she finds that there is no Na2HPO4, however there is a bottle of hydrate Na2HPO4 * 7H20. (FW=268.07) how many grams of this salt should she use in order to make 4 liters with the same phosphate concentration as above?
