how can I find the concentration of carbonate?

Question

In the titration of sea water, how can i find the conc. of carbonate.
11.97 ml of 0.00970 M sulfuric acid was added.
100 mL of sea water was used to titrate.

Answer 1

volume * molarity = volume * molarity

One mole of (CO3)-2 reacts one mole of H2SO4

To find the molarity of the Carbonate:

[(11.97 mL / 1000 mL/L) * 0.00970 moles/L] / (100mL / 1000 mL/L)

(0.01197 L * 0.00970 moles/L) / 0.100 L = 0.001161 moles/L
