(A corrosion technologist measured out at 50.00 ml sample of an Unknown brine and titrated it with 37.64 ml of 0.1024 M silver nitrate solution. Calculate the ppm salt NaCl in the sample. ?

This is the question

i know the answer for the messing concenteration but i dont know how to do the second Part calculate the ppm salt NaCl

Please any one help me for my question ??

Thx

1 ?g(microgram) per gram = 1 ppm (points per million)

So that means you'll have to check how many micrograms of NaCl you've got there. Then, you'll have make an assumption that the density of that solution is 1g/ml, which gives you 50 grams of solution.

Divide the micrograms of NaCl by 50 g of the solution and you've got yourself ppm's

the calculation is

titre value X Normality of AgNo3 X equivalent weight of Nacl X 1000000/ Volume of sample X 1000

you will get PPM
