question

A 25.00-ml sample of sea water is titrated with 2.50 M AgN0_3 solution, using K_2CrO_4, as an indicator, until the presence of excess Ag^+ is shown by the reddish color of Ag_2CrO_4 at the end point. The density of the sea water is 1.028 g/cc. Find the chlorinity and salinity of the sea water if 53.50 ml of AgNO_3 solution were used to complete the precipitation of silver halides.
