2. A water sample from the ocean has a DIC concentration

2. A water sample from the ocean has a DIC concentration of 2.60mm, a calcium concentration of 0.010m and a pH of 8.08. a. Calculate the concentration (in molal, m ) of carbonate. ( 3 marks) b. The Ksp for calcite in the sample is 1.85106. Determine the degree of saturation for calcite in the water mass. (2 marks) c. From your response in part (b), was this water sample collected from a location above (i.e., shallower than) or below (i.e., deeper than) the saturation depth? (1 mark)
