Ahot dog bun (volume 215 cm3) with a density of 0.11 g/cm3 is crushed in a picnic cooler into a volume of 135 cm3. what is the new density of the bun?

The answer to your question is:  density = 0.175 g/cm3

Explanation:

Data

v1 = 215 cm3

density1 = 0.11 g/cm3

v2 = 135 cm3

mass = ?

Formula

density = mass/volume

First, calculate mass

mass = density x volume   mass = 0.11 X 215 = 23.65 g

Now, calculate density with the second volume

 density = 23.65 g / 135 cm3

density = 0.175 g/cm3

answer; i believe that the correct answer is (a) potassium(k)

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
