Part D: Post lab Density Questions: Use the formula density = mass / volume for questions 1 \& 2 below: 1. A 4.91g sample of High-density lipoprotein (HDI) has a volume of 4.09mL. What is its density? Show your set-up for calculations. 2. A 4.91g sample of Low-density lipoprotein (LDL) has a volume of 4.68mL. What is its density? Show your set-up for calculations. 3. Using the values you got for the last two questions, why do you think one is called HDL and the other LDL? 4. It is said that you can tell the difference between a fresh and an old egg by where they will rest in a glass of water, because an old egg and a fresh egg have different densities. Knowing that a fresh egg's density is greater than 1.0g/mL, and an old rotten egg's density is less than 1.0g/mL, draw a picture that represents a fresh egg in water and an old egg in a glass of water
