Question

how do you find the total volume of water
total mass of water and density of water?

Answer 1

Please read the questions you post to see if they make sense. I have no idea what you're talking about. I could give a smart alecky answer and say "measure the water with a graduated cylinder, use a balance to determine the mass, and density = mass/volume" but I know those aren't the answers you are looking for. My point is that you must give us some idea of the problem and provide information to answer it. Perhaps I can help if you will clarify the question.
