Problem- In a qualitative analysis procedure, a chemist adds HCl to an unknown group of ions and then saturates the solution with H2S so that the solution is 0.2 M in HCl and 0.10 M in H2S.

(a) What is the [HS -] of the solution? (Note: The answer should be rounded to one significant figure. Be careful, 3.5 rounds up to 4, but 4.5 rounds down to 4!)

Write your solution in appropriate format and provide references
