Question
9:00 am Guiding questions: Do not answer these questions explicitly. Just be sure you have addressed all of these questions somewhere in your lab report. 1. What is density? 2. What kind of things could you measure that would allow you to calculate density? 3. What would it mean if an object floated in a liquid without sinking or rising to the surface? 4. What is your plan to estimate the accuracy of your measurement? 5. Of the two methods you devised discuss which you think is the best and the criteria you used for defining the best method. Safety Notes . If you choose any other chemicals except for those listed above, be sure to consult their MSDS for chemical and toxicity properties. Wear safety goggles and appropriate clothing at all times in the laboratory Dispose of wastes in the labeled containers. Do not pour any wastes down the drain.Explanation / Answer
Ans1. density can be defined as mass per unit volume of a substance.
Ans.2. For calculating density of a liquid, we take 1 ml of liquid by a syringe and measured its mass. then we calculate mass/ volume, we determine density.
Ans 3. If an object is floating on the surface of liquid, that means the density of the object is lesser than the density of the liquid.
