Math10, I see you are back today. What about your thread:
https://www.physicsforums.com/threads/find-the-quantity-of-salt-in-the-tank.792459/

Have you solved it? Do you have additional questions? Are you going to return to that thread or just abandon it after some of us have spent our time with it?

Yes, this is correct. My earlier response, which is now deleted, was incorrect. Sorry to have misled you.
