Ok, take on liter. It mass is then 1025 grams, so it has salt in the mass amount of .03*1025. Then the moles of sale is that mass divided by 58.44.
Molarity=normality=molesSalt/1
assuming that sea water is an aqueous solution of NaCl its density is 1.025g/mL at 20C temperature and NaCl concentration is 3.5%(by mass), the normality of the sea water?
