Molecular mass

Using periodic table found in your textbook, calculate (to 2 decimal places) the molecular mass for each of the compounds used to make PBS.

Create the following table and fill it in with the mass of each component required to make 1 liter of 10 x PBS (the recipe for 10x PBS is below question 2)

and their final molar concentration in the buffer calculated as described above.
