Student Name Section: Date: i. Why do you expect the two calculations for the density of water to be very similar? Wh will they not be exactly the same? 2. What is the density of water? 3. Why is liquid? it important to start with a dry cylinder when determining the density of the unknown 4. What is the mathematical formula for determining density? Considering how close some of the reference density values are, why is it important to obtain as many significant figures as possible in your measurements? 5. Experiment 2 Density: Will It Float?Explanation / Answer
Determining density of a liquid
1. Density of water would be similar in every run and close to 1.0 g/ml of literature value due to the same mass and volume values for water. However, the density values would not be exactly the same as the error in measurement of the mass and the volume of liquid would result in slight variation of the final calculated density values.
2. Density of water = mass of water/volume of water = 1 g/ml
3. To avoid any error due to any previous liquid left in the cyllinder, it is suggested to use a clean and dry cyllinder when we begun measuring density of a new liquid.
4. Mathermatical formula for density = mass of liquid (g)/volume of liquid (ml)
5. Since the reference density values are very close to one another it is important to get very accurate values and thus greater number of significant values must be noted down to determine which liquid is under consideration in the experiment.
