Assuming the following materials will not mix, show how the materials would "stack up" in a graduated cylinder.
air 0.001g/cm3, gycerin 1.26g/cm3,corn syrup g/cm3,wood 0.85 g/cm3,steel7.81g/cm3,rubber 1.34 g/cm3,ice0.94 g/cm3,water 1.0 g/cm 3
corn oil 0.93g/cm3

Density is mass per unit volume.

Its formula is  

Density = Mass / Volume

Its units can be kg/L  or kg/() or g/mL or g/()

Density of various substances are given. The more denser substance goes to the bottom of the graduated cylinder.  

Air on the top then comes  Wood followed by  Corn oil followed by  Ice and then  Water followed by  Glycerin then  Rubber then  Corn syrup and at last  Steel at the bottom  which will more denser than all the substances mentioned above.

The staking up of the substances is in the order mentioned below in the tabular column

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
