How did the instructor obtain 0.00196%? I got the M correct. I am only confsused on what math she did to get that. I know you can assume 100g or 100mL solution for (w/v) and (w/w). If you can please show all of your steps clearly that would be so helpful!
3. A sulfuric acid solution was prepared by transferring 0.0196 g of acid to a 1-L v flask and diluting the solution to the mark. Calculate the concentration of acid in the solution in all of the units mentioned in Question 1. (Assume the sulfuric acid dissociates completely) Answers: 2.00 x 10-4 M, 0.00196% (w/v), 0.00196% (w/w), 19.6 ppm
