Precipitation reactions

The mass% of Cl- in seawater sample is determined by titrating 25.00mL of seawater with AgNO3 solution, causing a precipitation reaction. An indicator is used to detect the end point, which occurs when free Ag+ ion is present in solution after all the Cl- has reacted. If 53.63mL of 0.2960M AgNO3 is required to reach the end point, what is the mass percent of Cl- in the seawater (d of seawater = 1.024g/mL)?


I tried many ways, but couldnt find the right answer, somebody pls help me and show how you do it, via youtube video for example?


A lot of thanks!
