(1) What type of hydrometer did you use in this lab exercise? What is the brand and model? (2) Include a photograph of your hydrometer in use to earn full credit for this lab exercise, (10 point penalty if photo is missing). Note that "in use" means floating in a liquid at a time when you're taking a measurement. (3) Is your hydrometer floating freely when you make the measurements? (Use a thin plastic bottle or thin clear vase if your cup is too shallow for the hydrometer to float freely. Hint: the reading should be close to 1.000 for pure water if it is working correctly.) (4) When you measured the specific gravity of the three glasses of water with your hydrometer, what did you observe? Report the numbers that you recorded in a table. This must be reported out to three decimal places. (5) What values did you see for specific gravity when you measured the three different glasses of water, slightly salty water, and very salty water with the test strips? (6) Include a photograph of the three test strips that you used for measuring specific gravity of the three solutions. Please include the color chart for
